What is gesso? a. A technique used by many Renaissance artists b. A medium used as a surface preparation or primer for a paintin
Sholpan [36]

Gesso is a white paint blend that comprises pigment, chalk and gypsum. It is a medium utilised for surface preparation and as a primer for a painting.

<h3>What are the uses of gesso?</h3>

Gesso is widely utilized for preparing surfaces and as primers by painters. They were used by painters and artists earlier to make canvas, boards for painting purposes.

It was first formulated by chalk powder dust and pigment derived from the animal skin. They are widely used because of their adhering properties.

The use of the gesso makes the paint adhere to the canvas and the board surfaces and also, makes the surface textured.

Therefore, option b. it is used for preparing the surface is correct.

A 1.000 kg sample of nitroglycerine, C3H5N3O9, explodes and releases gases with a temperature of 1985°C at 1.100 atm. What is th
Ede4ka [16]

Answer:

742.2 L

Explanation:

First we must find the number of moles of nitroglycerine reacted.

Molar mass of nitroglycerine= 227.0865 g/mol

Mass of nitroglycerine involved = 1×10^3 g

Number of moles of nitroglycerine= 1×10^3g/227.0865 g/mol

n= 4.40361 moles

T= 1985°C + 273= 2258K

P= 1.100atm

R= 0.082atmLmol-1K-1

Using the ideal gas equation:

PV= nRT

V= nRT/P

V= 4.40361× 0.082× 2258/1.1

V= 742 L

1. How many joules must be added to 10.0 g of water to raise its temperature from 10°C to<br> 15°C?
weqwewe [10]

Answer:

209.3 Joules require to raise the temperature from 10 °C to 15 °C.

Explanation:

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree.

Formula:

Q = m × c × ΔT

Given data:

mass of water = 10 g

initial temperature T1= 10 °C

final temperature T2=  15 °C

temperature change =ΔT= T2-T1 = 15°C - 10°C = 5 °C

Energy or joules added to increase the temperature Q = ?

Solution:

We know that specific heat of water is 4.186 J/g .°C

Q = m × c × ΔT

Q = 10 g × 4.186 J/g .°C × 5 °C

Q = 209.3 J

How many moles are equal to 89.23g of calcium oxide, CaO?
Katen [24]

1.59moles

Explanation:

Mass  of CaO = 89.23g

Unknown

Number of moles = ?

Solution:

The mole is a unit of measurement in chemistry used to delineate the number of particles an atom contains.

A mole of a substance contains the avogadro's number of particles.

Number of moles = \frac{mass}{molar mass}

Molar mass of CaO = 40 + 16 = 56g/mol

  Number of moles = \frac{89.23}{56} = 1.59moles
