Anna stated that ionic compounds have high melting points and low boiling points. She said that this demonstrates that ionic com

Answer: Anna stated that ionic compounds have high melting point and low boiling point. The error in the statement is that ionic compound have low boiling point, instead ionic compounds have high boiling point, because in an ionic compound, the force of attraction working between two ions is very strong and hence the bonds present are very strong, and a lot of energy is needed to break them

Which properties of gold make it valuable for many scientific and industrial uses?
Svetach [21]
<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ For scientific uses, the main key property is that gold is unreactive. Gold is naturally occurring and found in nature. It is highly unreactive. This is also a beneficial quality for industrial uses such as making jewelry. Gold has tarnish resistance and takes a lot longer to dull in color than many other metals. Also, Gold is highly ductile meaning it can be drawn into thin wires to create detailed and delicate jewelry.

If 250 milliliters of Calcium Hydroxide is titrated with 345 milliliters of 0.75 molarity hydrobromic acid, what is the concentr
Bingel [31]
The balanced neutralization reaction here is:

Ca(OH)2 + 2HBr --> 2H2O + CaBr2

Notice that two moles of Her are required to neutralize every one mole of Ca(OH)2. This means that for however many moles of Her reacted, HALF as many moles of Ca(OH)2 reacted as well.

Moles of HBr reacted = 0.75 M x 0.345 L = 0.259 mol

Moles of Ca(OH)2 reacted = 0.259 mol / 2 = 0.130 mol

Concentration of Ca(OH)2 = 0.130 mol / 0.250 L = 0.52 M

When the pressure of a gas decreases, which quantity will increase, assuming all other variables are held constant?
frosja888 [35]

I don't think the answer is in one of the options- unless I am reading it wrong and there is a 'V' option.

The volume (V) of gas increases when the pressure of the gas decreases assuming all the other variables are held constant.

I hope this helps!
