Being less reactive than chlorine but more reactive than iodine, bromine reacts vigorously with metals, especially in the presence of water, to give bromide salts.

Calcium metal reacts with water, evolving hydrogen gas at a rate rapid enough to be noticeable, but not fast enough at room temperature to generate much heat.

In water solutions of acids, where this salt is soluble, calcium reacts vigorously.

The actual reaction is more complicated and involves the bicarbonate ion ( HCO < sub > 3 </ sub >< sup >-</ sup >) that forms when CO < sub > 2 </ sub > reacts with water at seawater pH:

In addition to igniting spontaneously in air, it reacts explosively with water even at low temperatures, more so than other members of the first group of the periodic table.

Lithium reacts with water easily, but with noticeably less energy than other alkali metals do.

Lanthanum is quite electropositive and reacts slowly with cold water and quite quickly with hot water to form lanthanum hydroxide:

Like its lower periodic table group neighbor calcium, magnesium reacts with water at room temperature, though it reacts much more slowly than calcium.

She helped him with the dishes, then he brought more water in from the spring before it got dark.

Many of them, in increasing panic, came running with water in their hats in a ludicrous effort.

Then Little Billy began shouting orders to round up the ponies and fill the water buckets and for the cooks to hurry up with the meal.

The town was about what Wilson expected: one main street with its rows of false-fronted buildings, a water tower, a few warehouses, a single hotel ; ;

The two tall brothers waited silently while their mother handed Gran her cold snack and water jug, placed the chamber pot beside her feet, and returned to her place at the front of the wagon with Alice.

The water in Thor's big swimming pool had been covered with a blanket of thick, foamy soapsuds -- fashioned, of course, from zing -- Joyce had dived from the board into the pool, then swirled and cavorted in her luxurious `` bath '' while cameras rolled.

Beaten with fear and sound and wet and chill, they crawled to the hurricane deck and looked out haggardly at a world of water that reached clear to the surrounding hills.

Then he took off his wet boots and dropped down into the water to talk with the beasts, needing their comfort more than they needed his.

Already our leaky lifeboat was filled with five inches of water.

For a brief period each year, the rays of the sun are warm enough to melt some of the snows piled a mile deep at the base of the headwalls, and then the pinnacles glisten in the daytime at high noon, and billions of gallons of water begin their slow seepage under the glaciers and across the rockstrewn hanging valleys on their long, meandering journey to the sea -- running east past the sky-carving massifs of Gurla Mandhata and Kemchenjunga, then turning south and curling down through the jungles of Assam, past the Khasi Hills, and into Bengal, past Sirinjani and Madaripur, until the hard water of the melting snows mingles with the soft drainage of fields and at length fans out to meld with the teeming salt depths of the Bay of Bengal.

This was the land of the sladang, the great water buffalo with horns forty inches across the spread.

Now, the next morning, they were anchored at The Elbow and the boat was riding directly over the underwater ledge where the green water turned to deepest blue and the cliff dropped straight down 600 fathoms, with the weighted line beside it ; ;

Awkwardly with one hand Matsuo got the cap back on the water bottle.

He had found a depression with rain water in it.

Travelers entering from the desert were confounded by what must have seemed an illusion: a great garden filled with nightingales and roses, cut by canals and terraced promenades, studded with water tanks of turquoise tile in which were reflected the glistening blue curves of a hundred domes.

To return now to the four-element physics, a mixture of muddy, frothy water will, when standing in a jar, separate out with earth at the bottom, water on top, and the air on top of that.

It is covered ( partly ) with water, air is atop of that.

They kicked their horses through the deep water with their bare heels, drove the Rebels out of their rifle pits and captured four men.

Laura Keene brushed by him with the glass of water.

We tumbled to a stop in Deacon Gordon's cow hole, a low-lying bit of pasture with a muddy pool of water in its middle.

One type of cement, called pozzolana, consisted of water, lime, sand, and volcanic rock.

Concrete is a composite construction material composed primarily of aggregate, cement, and water.

Combining water with a cementitious material forms a cement paste by the process of hydration.

Pervious concrete is a mix of specially graded coarse aggregate, cement, water and little-to-no fine aggregates.

Hydraulic cements ( e. g., Portland cement ) harden because of hydration, chemical reactions that occur independently of the mixture's water content ; they can harden even underwater or when constantly exposed to wet weather.

The chemical reaction that results when the anhydrous cement powder is mixed with water produces hydrates that are not water-soluble.

Rosendale cement was extremely popular for the foundation of buildings ( e. g., Statue of Liberty, Capitol Building, Brooklyn Bridge ) and lining water pipes.

Concrete is a composite material consisting of aggregate ( gravel and sand ), cement, and water.

As a result, wet cement is strongly caustic and can easily cause severe skin burns if not promptly washed off with water.

Green cement is a cementitious material that meets or exceeds the functional performance capabilities of ordinary Portland cement by incorporating and optimizing recycled materials, thereby reducing consumption of natural raw materials, water, and energy, resulting in a more sustainable construction material.

Industries: small-scale production of textiles, soap, furniture, shoes, fertilizer, apparel, food-products, non-alcoholic beverages, mineral water, cement ; handwoven carpets ; natural gas, coal, copper

Major industrial activities include sugar refining, rum distilling, food processing, cement and brick manufacture, mineral water bottling, beverage making, chemical making, textile manufacture & electronics assembly.

The larger enterprises produce beer, soft drinks, cigarettes, hoes, wheelbarrows, soap, cement, mattresses, plastic pipe, roofing materials, textiles, and bottled water.

To make the roads the Romans used stones, broken stones mixed with cement and sand, cement mixed with broken tiles, curving stones — so the water could drain, and on the top they used tightly packed paving stones.

ASTM C 150 defines portland cement as " hydraulic cement ( cement that not only hardens by reacting with water but also forms a water-resistant product ) produced by pulverizing clinkers consisting essentially of hydraulic calcium silicates, usually containing one or more of the forms of calcium sulfate as an inter ground addition.

The rate of initial reaction ( up to 24 hours ) of the cement on addition of water is directly proportional to the specific surface area.

Many different types of glue held these sections together most commonly Irish glue and bone glue until hilton glue or cement glue was introduced because of its water proof qualities.

When mixed with a small amount of water, the cement hydrates to form microscopic opaque crystal lattices encapsulating and locking the aggregate into a rigid structure.

When the cement paste exposed to the air and meteoric water reacts with the atmospheric CO < sub > 2 </ sub >, portlandite and the Calcium Silicate Hydrate ( CSH ) of the hardened cement paste become progressively carbonated and the high pH gradually decreases from 13. 5 – 12. 5 to 8. 5, the pH of water in equilibrium with calcite ( calcium carbonate ) and the steel is no longer passivated.
