Answer:

Density of concentrated H2SO4 = 1.99g/cm^3 = 1991.79Kg/m^3

Explanation:

mass of empty flask = 78.23g mass of flask filled when with water = 593.63g.

mass of flask filled when with concentrateds sulfuric acid, H2SO4 = 1026.57g

Mass of water = (mass of flask filled when with water) -

(mass of empty flask) = 593.63g - 78.23g = 515.4g

Volume of flask = volume of water = volume of concentrateds sulfuric acid, H2SO4 =

(mass of water)/ density of water) = 515.4g/1.00g/cm^3 = 515.4cm^3

The density of concentrated sulfuric acid is given by

Density of concentrated H2SO4 = (mass of H2SO4) ÷ (volume of H2SO4) = 1026.57g/515.4cm^3 = 1.99g/cm^3 = 1991.79Kg/m^3

Write the ground-state electron configuration for the chloride ion.You may write either the full or condensed electron configura
dalvyx [7]

Answer:

1s^22s^22p^63s^23p^6

Explanation:

Chlorine is the element of group 17 and third period. The atomic number of chlorine is 17 and the symbol of the element is Cl.

The electronic configuration of the element chlorine is:-

1s^22s^22p^63s^23p^5

Chloride ion is formed when chlorine atom gain one more electron. So, the ground-state electron configuration for the chloride ion is:-

1s^22s^22p^63s^23p^6

A bowling ball is pushed with a force of 22.0 N and accelerates at 5.5 m/s^2 what is the mass of the bowling ball?
Kruka [31]

Data:

F (force) = 22.0 N

m (mass) = ? (in Kg)

a (acceleration) = 5.5 m/s²

We apply the data to the Resultant Force formula, we have:

4.0 kg

I hope this helps. =)

How many liters of carbon dioxide can be produced if 37.8 grams of carbon disulfide react with excess oxygen gas at 28.85 degree
alekssr [168]
37.8 grams of CS2 equals to 37.8/76=0.5 mole. So the products have 0.5 mole CO2 which is 11.2 liters at STP. So according to the gas law, the volume at given condition is 12.4 liters. So the answer should be 12.2 liters.

Which species is classified as a Arrenhius base? 1. CH3OH 2. LiOH 3. PO43- 4. CO32-
Otrada [13]

Answer:

2. LiOH

Explanation:

An Arrhenius base is a substance or chemical compound which increases  the number of OH- ions when added in water.

LiOH or lithium hydroxide is one of the strong Arrhenius base as it ionizes completely or near-completely in solution. When LiOH is added to water , it dissociates into lithium (Li+) and hydroxide (OH−) ions.

Hence, the correct answer is 2. LiOH.
