A metamorphic rock can turn into an igneous rock if it becomes hot enough to melt. Then, when it cools enough to become solid the result will be an igneous rock. An igneous rock can become metamorphic, if it is under pressure when it is heated. The pressure will keep the rock from melting but will allow the atoms to unite with our atoms forming new minerals when the rock cools. The resulting metamorphic rock will have some new minerals that the igneous didn't have. The new minerals will have a ordered physical arrangement unlike the random mixture of an igneous rock.

Be(OH)2 is solid why?

pickupchik [31]

Answer:

no it's not solid rather it's an aqueous

Explanation:

B/c Barium hydroxide is used in analytical chemistry for the titration of weak acids, particularly organic acids. Its clear aqueous solution is guaranteed to be free of carbonate, unlike those of sodium hydroxide and potassium hydroxide, as barium carbonate is insoluble in water.

What is the name of the ionic compound AlBr3?

Aleksandr [31]

Answer: Correct name will be is aluminum bromide

Explanation:

In a molecular formula , $AlBr_3$

Aluminium atoms present = 1

Bromine atoms present = 3

Charge on aluminium is +3 and charge on bromine is -1.

While naming:

Name of the cation is written first. Simple name of the element is written
After name of cation name of an anions written with suffix 'ide' in the end.

So, the name of $AlBr_3$ will be aluminium bromide.

The theoretical yield of a reaction is the amount of product obtained if the limiting reactant is completely converted to produc

Elis [28]

Answer: 9.9 grams

Explanation:

To calculate the moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}$

a) moles of $H_2$

$\text{Number of moles}=\frac{8.150g}{2g/mol}=4.08moles$

b) moles of $C_2H_4$

$\text{Number of moles}=\frac{9.330g}{28g/mol}=0.33moles$

$H_2(g)+C_2H_4(g)\rightarrow C_2H_6(g)$

According to stoichiometry :

1 mole of $C_2H_4$ combine with 1 mole of $H_2$

Thus 0.33 mole of $C_2H_4$ will combine with = $\frac{1}{1}\times 0.33=0.33$ mole of $H_2$

Thus $C_2H_4$ is the limiting reagent as it limits the formation of product.

As 1 mole of $C_2H_4$ give = 1 mole of $C_2H_6$

Thus 0.33 moles of $C_2H_4$ give = $\frac{1}{1}\times 0.33=0.33moles$ of $C_2H_6$

Mass of $C_2H_6=moles\times {\text {Molar mass}}=0.33moles\times 30g/mol=9.9g$

Thus theoretical yield (g) of $C_2H_6$ produced by the reaction is 9.9 grams
