If you have a density of 100 kg/L and a mass of 1000 g what is the volume (please explain)

Chemistry
1 answer:
olchik [2.2K]3 years ago
6 0

Answer:  Volume =  0.01L

Explanation:

The density of a substance is given by; Density =  Mass / Volume.

In this question, Mass = 1000g, Volume = ? and Density = 100 Kg/L

For the units to be uniform, we convert 1000g to Kg = 1Kg

Therefore, Volume = Mass / Density =  1Kg / 100Kg/L = 0.01L

g Nitrogen in the atmosphere consists of two nitrogen atoms covalently bonded together (N2). Knowing that nitrogen is atomic num
vichka [17]

Explanation:

Since, the atomic number of nitrogen is 7 and its electronic distribution is 2, 5. So, in order to attain stability it needs to gain 3 electrons.

Hence, when it chemically combines another nitrogen atom then as both the atoms are non-metals. So, sharing of electrons will take place.

Also, there is no difference in electronegativity of two nitrogen atoms. Hence, compound formed N_{2} is non-polar covalent in nature.

Which one of the following metals would NOT displace hydrogen from a dilute solution of HCl? 1. Ag 2. Fe 3. Al 4. Ni
jolli1 [7]

Answer:

Ag

Explanation:

To determine which element will displace hydrogen from a dilute acid, we need to make reference to the activity series or the electrochemical series. The activity series is a list of metallic ions according to their electropositivity.

This means elements are ranked here based on how electrically positive they are. Hence, an element above another element is relatively more electropositive than the one under it. For example calcium is less electropositive compared to sodium as calcium is found under sodium in the list.

Now, for an element to displace hydrogen, it means the particular element is more electropositive than hydrogen on the activity series. All the elements in the options are in a greater position relative to hydrogen on the activity series except silver. This means it cannot displace hydrogen from a dilute mineral acid

HCI+CaCO3=CaCl2+H2O+CO2<br>​
Nookie1986 [14]

Answer:

2 HCl + CaCO3  = CaCl2 + H2O + CO2

Explanation:

On the right side we have 2xCl, to get the same amount we will multiply HCl on the left side by 2.

This will give us 2xH on the left side; we also have 2xH on the right side ( in H2O).

On both sides we have 1x Ca; 1x C.

On the left side we have 3XO (in CaCO3), on the right side we have 1O in H20 and 2xO in CO2, so 3x O on the right side as well.

The reaction is balanced.

What is the heat needed to raise the temperature of 24.7 kg silver from 14.0 degrees Celsius to 30.0 degrees Celsius? Specific h
ELEN [110]

Answer:

Q=93.3kJ

Explanation:

Hello,

In this case, by knowing that the heat due to a change of temperature is given by:

Q=mCp\Delta T

Whereas Q accounts for the heat, m for the mass, Cp the heat capacity and ΔT for the change in temperature. In such a way the required heat results:

Q=24.7kg*236\frac{J}{kg^oC}*(30.0-14.0)^oC*\frac{1kJ}{1000J} \\Q=93.3kJ

Best regards.
