Answer: 15N

Explanation:

The formula to calculate force in this scenario will be:

Force = Mass × Acceleration

where,

Mass = 6kg

Acceleration = 2.5m/s

We then put the values of mass and the acceleration in the formula. This will be:

F = ma

F = 6 × 2.5

F = 15N

Therefore, the force required to move the bowling ball will be 15Newton.

Answer:

Thus, we can say that the element is calcium. This can be clearly understood as ionic compounds have high melting and boiling points in general such as calcium oxide.

Answer:

Answer:

A 15.75-g piece of iron absorbs 1086.75 joules of heat energy, and its temperature changes from 25°C to 175°C. What is the specific heat capacity of iron?

Explanation:

The amount of heat absorbed by the gold is 339.1 joules, which was calculated by the formula of specific heat capacity.

Specific heat capacity, often just called “specific heat”, is the amount of heat energy required to raise the temperature of one unit of mass of a substance by one degree Celsius (or one Kelvin).

To calculate the amount of heat absorbed by the gold, we can use the formula:

Q = m × c × ΔT

where:

Q = heat absorbed (in joules)

m = mass of the gold (in grams)

c = specific heat capacity of gold (in joules per gram per degree Celsius)

ΔT = change in temperature of the gold (in degrees Celsius)

The specific heat capacity of gold is 0.129 J/g°C.

Substituting the given values into the formula, we get:

Q = 15.5 g × 0.129 J/g°C × (177.4°C - 4.5°C)

Q = 15.5 g × 0.129 J/g°C × 172.9°C

Q = 339.1 J

Therefore, the amount of heat absorbed by the gold is 339.1 joules.

Answer:

0.21 mole of NaCl

Explanation:

From the question,

using Avogadro's Constant,

1 mole of every compound contains 6.02×10²³ molecules of that compound.

I.e

1 mole of NaCl ⇒ 6.02×10²³ molecules of NaCl

x moles of NaCl ⇒ 1.25××10²³ molecules of NaCl

Solving for x,

x moles of NaCl = (1 mole of NaCl)×(1.25×10²³ molecules of NaCl)/(6.02×10²³ molecules of NaCl)

x moles of NaCl = (1×1.25×10²³)/6.02×10²³

x = 0.208 mole of NaCl

x ≈ 0.21 mole of NaCl

Answer:3.4

Explanation:

Answer:

62 L

Explanation:

We are given that:

n = 2.3 mol

R = 0.082 L*atm/(mol*K), the ideal gas constant in the required units

T = 290 K

P = 0.89 atm.

therefor:

V = nRT/P

= [(2.3 mol)(0.082 L*atm)(290 K)/(mol*K)]/(0.89 atm)

= 62 L

The volume of 2.3 mol CL2 will be 62 L.

A three-dimensional element's area of coverage. The measurement of volume is done in cubic units. Decibels are a unit of measurement for the volume of sound.

Calculation of volume.

Volume can be determined by using the formula.

PV = nRT

where, P = pressure, V = volume, n = number of moles, R = gas constant and T = temperature,

It is given that, n = 2.3 mol, T = 290 K and P = 0.89 atm.

Put the value of given data in volume equation,

V = n RT/ P

V = 2.3 mol × 0.082 × 290 /0.89

V = 62 L.

Therefore, the volume will be 62 L.

Answer:

27.99 dm³

Explanation:

Applying

PV = nRT................ Equation 1

Where P = Pressure, V = Volume, n = number of mole, R = molar gas constant, T = Temperature.

From the question, we were aksed to find V.

Therefore we make V the subject of the equation

V = nRT/P................ Equation 2

Given: n = 1.31 moles, T = 37°C = 310K, P = 904 mmHg = (904×0.001316) = 1.1897 atm

Constant: R = 0.082 atm.dm³/K.mol

Substitute these values into equation 2

V = (1.31×310×0.082)/(1.1897)

V = 27.99 dm³
