4 0

Answer:

as the greatest heat capacity? a. 1,000 g of water b. 1,000 g of steel c. 1 g of water d. 1 g ... +1. kvargli6h and 1 other learned from this answer. Answer: a. 1,000 g of water ... Heat capacity of steel = 0.49 J/gram^0C. Hence 1,000 g of water will have greatest heat capacity.

You have a 1.153 g sample of an unknown solid acid, HA, dissolved in enough water to make 20.00 mL of solution. HA reacts with K
seropon [69]

Answer:

HA +  KOH  →  KA  +  H₂O

Explanation:

The unknown solid acid in water can release its proton as this:

HA  +  H₂O  →  H₃O⁺  +  A⁻

As we have the anion A⁻, when it bonded to the cation K⁺, salt can be generated, so the reaction of HA and KOH must be a neutralization one, where you form water and a salt

HA +  KOH  →  KA  +  H₂O

It is a neutralization reaction because H⁺ from the acid and OH⁻ from the base can be neutralized as water

In a chemical formula such as C6H12O6 and H2O, what do you call the little numbers below the normal line of text.
Morgarella [4.7K]

These are called subscript number.

That is the number below the normal line of test are called subscript number.

This number indicate the indicate the number of atoms of the element present in the chemical formula.

In both of these C₆H₁₂O₆ and H₂O, the number written below the line of the text are called subscript numbers.

A car is traveling at a speed of 95 mi/h. If there are 0.62137 miles (mi) in a kilometer,
SIZIF [17.4K]

Answer:

42 m/s

Explanation:

To we convert units for speed we can use dimensional analysis. First thing we do is seperate the measurement into a fraction. After this we can multiply by 1km over 0.62137 miles. We do this so that the miles cancel out.

\frac{95mi}{h} × \frac{1km}{0.62137mi} = \frac{95km}{0.62137h}

After this we can use a conversion factor and divide by 3.6.

\frac{95km}{0.62137h} ÷ 3.6 = 42 m/s
