What is another chloride that could be used instead of the calcium chloride dihydrate to produce a solid precipitate with aqueou
Natali [406]

cesium chloride is another chloride that could be used instead of the calcium chloride dihydrate to produce a solid precipitate with aqueous sodium carbonate

A mineral salt called cesium chloride (CsCl) is occasionally ingested or administered intravenously to cancer patients seeking alternative therapies. However, the FDA has not yet approved any cesium chloride products to treat cancer or other disorders.

In isopycnic centrifugation, cesium chloride is a common medical compound used to separate different forms of DNA. It is a reagent used in analytical chemistry to distinguish ions based on the hue and shape of the precipitate.

Cesium chloride is not proven to be effective in treating cancer. As an alternative to chemotherapy for cancer, cesium chloride is pushed. Supporters assert that cesium prevents tumor cells from proliferating by neutralizing the poisons they release.

Water wheels convert the kinetic energy of moving water into which form? A. potential energy B. chemical energy C. gravitational
denpristay [2]

Answer:

the answer is mechanical energy

Explanation:

A water wheel converts the kinetic energy of moving or falling water into mechanical energy. This mechanical energy is used for powering the mill.Water wheels have wooden or metal wheels that have buckets or blades attached around them. They are placed in a river or lake. The force of the water rotates the wheel. As the wheel moves, it turns an axle attached horizontally to the wheel. The axle in turn moves the system of gears that operate the functioning of mills. Waterwheels were used for preparing fiber and crushing ore.

A compound is formed when 171.2g of carbon reacts with 28.8 g of hydrogen what is the mass percent of hydrogen in the compound
PolarNik [594]
Hi.

You can calculate mass percent by dividing the mass by the total mass of the compound & multiplying by 100.

28.8 ÷ (171.2 + 28.8) = 0.144

0.144 · 100 = 14.4

I believe the mass percent of the hydrogen in the compound is 14.4%
