Answer: -
Magnesium reacts very slowly to form magnesium hydroxide and hydrogen gas. The balanced chemical equation for the reaction is
Mg + 2H₂O → Mg(OH)₂ + H₂
Explanation: -
Chemical symbol of magnesium = Mg
Chemical formula for magnesium hydroxide = Mg(OH)₂
Chemical formula for hydrogen gas = H₂
The other reactant with Mg must be water H₂O.
Thus the balanced chemical equation for the reaction is
Mg + 2H₂O → Mg(OH)₂ + H₂
Answer:
false
Explanation:
false, only a small percentage of mutations cause genetic disorders—most have no impact on health or development. For example, some mutations alter a gene's DNA sequence but do not change the function of the protein made by the gene.
Answer:
2.7005 g/cm²
explanation: as we know density=mass/volume
Ice melts when heat energy causes the molecules to move faster, breaking the hydrogen bonds between molecules to form liquid water.
<span>The constant bombardment of gas molecules against the inside walls of a container produces Pressure.
Explanation:
Pressure is defined as Force per unit Area.
P = F / A
In case of gases, the gas molecules have high Kinetic Energy and they move with high velocity. This cause them to strike against the inside wall of the container. Pressure is directly proportional to temperature. Increase in temperature cause to increase the Kinetic Energy of molecules, Hence, the rate of collisions increases resulting in increasing the pressure.</span>
