Well they can rust if you don’t dry properly. But they can burn your hands because they conduct heat.

An object has a density of 1.75 g/mL. Will it float on water? Why?

Advocard [28]

Answer:

The object will not float in water because the density of the object is greater than that of water.

Explanation:

Density of object = 1.75 g/mL

Density of water = 1 g/mL

The Density of the object is 1.75 g/mL and that of water is 1 g/mL. This implies that the object is denser (i.e heavier) than water. Therefore, the object will not float in water, rather it will sink in water since it's density is greater than that of water.

Which hydrocarbon belongs to the Alkyne homologous series?

Ira Lisetskai [31]

Answer:

(A) CHCH

Explanation:

Hello,

Alkynes are formed when triple bonds are formed between carbons, it means that due to the triple bonds, three bonds are already exhausted and carbon atoms need four bonds to attain the octet, for that reason, an extra bond is allowed. Now, such extra bond, when talking about hydrocarbons is filled with hydrogens, for that reason the alkyne should be (A) CHCH as it also accomplishes the following formula which is not accomplished by the rest of the options:

$C_nH_{2n-2}$

Since n=2, we have:

$C_2H_2$

Which matches with CHCH.

Best regards.

The volume of a gas is 650. mL at 1.14°C. What will the volume be a 75.0°C?

tia_tia [17]

Answer: The final volume of the gas is 825.12 mL

Explanation:

To calculate the final temperature of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$
