Answer:
The correct answer is C) insulator
Explanation:
The characteristics of metals consist of conductivity (for example of heat), malleability (deformation property) and ductility (stretching capacity).
First, you write the balanced equation for the reaction
2HCl + Mg(OH)2 ----->MgCl2 + 2H2O
Next, find the number of moles of Magnesium Hydroxide
Number of moles of Mg(OH)2 =
mass / Mr = 3.33 / 24 +2(1+16)
=0.0574 mol
Find the mole ratio between HCl and Mg(OH)2 which is 1:2
Number of moles of HCl = 0.0574 x 2 = 0.1148 mol
Mass of HCl = Mr x no. of moles
=0.1148 x (1+35.5)
=4.19 g
An increase in the number of gas molecules in the same volume container increases pressure. A decrease in container volume increases gas pressure. An increase in temperature of a gas in a rigid container increases the pressure.
what is that????????????????
