Explanation:

Radioactive tracers are widely used to diagnose industrial reactors, for instance by measuring the flow rate of liquids, gases and solids. A radioactive tracer is a chemical compound in which one or more atoms have been replaced by a radioisotope.

Answer: 4,3,2

Explanation:

Answer:

See Explanation

Explanation:

According to Avogadro's law;

V1/n1 = V2/n2

V1 = 5.0 L

n1 = 15.0 moles

V2= ?

n2 = 30.0 moles

V1n2 = V2n1

V2 = 5 * 30/15

V2 = 10 L

2) 1 mole of N2 occupies 22.4 L

3 moles of N2 occupies 3 * 22.4/1 = 67.2 L

3) 1 mole of O2 occupies 22.4 L

x moles occupies 201.6 L

x = 1 mole* 201.6 L/22.4 L

x = 9 moles

4) Density of a gas = mass/volume

Density of a gas = 39.95 g/22.4 L = 1.78 g/L

Answer:

two hydrogen can bonded with oxygen to form H2O

Answer:

If you pass bromine vapour over hot iron, a similar but slightly less vigorous reaction happens, this time producing iron(III) bromide. Anhydrous iron(III) bromide is usually produced as a reddish-brown solid. Again the iron has been oxidised to an oxidation state of +3.

Answer:

0.188mol

Explanation:

Using the formula;

mole = mass/molar mass

Molar mass of hypomanganous acid. (H3MnO4) = 1(3) + 55 + 16(4)

= 3 + 55 + 64

= 122g/mol

According to this question, there are 22.912g of H3MnO4

mole = 22.912g ÷ 122g/mol

mole = 0.188mol

Answer:

4.00M NaOH

Explanation:

A 50-ml amount of 40.0M NaOH contains

(40.0 mol NaOH/1 L)×(0.0500L) = 2.00 mol NaOH

Adding enough water to make a 500.0 mL NaOH solution, the new concentration of this solution is

2.00 mol NaOH/0.5000 L = 4.00M NaOH

Answer:

2,325.6

Explanation:

You use the formula

Q =mco

M =mass =68

C=0.9

O=temperature increases =93-55=38

Then multiple all this 3

Q=68*0.9*38

The number of joules of heat that is needed to heat 68.00 grams of aluminum foil is 2,325.6.

The amount of energy needed to raise the temperature of one gram of a substance by one degree Celsius.

By the formula of heat

Q = mct

The mass of aluminum is 68.00

the difference in temperature is 93.00 °C - 55.00 °C = 38.00

The specific heat is 0.90 J/g

Putting the values in the equation

[tex]Q = mct\\\\Q = 68.00 \times 0.90 \times 38.00 = 2325.6[/tex]

Thus, the joules of heat is 2325.6 J.

Answer:

Energy of Movement.

Explanation:

Have a great day!

Answer:

14.6

Explanation:

I just took the test

The amount of heat to raise the temperature is 14.7J.

The specific heat capacity of a substance is the quantity of heat needed to raise the temperature of a unit quantity of the substance by one degree. Calling the amount of heat added Q, which will cause a change in temperature ∆T to a weight of substance W, at a specific heat of material Cp, then Q = w x Cp x ∆T

By applying the formula, we get

Q = w x Cp x ∆T

Q = 300 * 2.46 * 20/1000

Q = 14.760J

Heat is energy that is transferred from one body to another as the result of a difference in temperature.

Answer:

The grams of sodium chloride that will be made is 292.5 g. calculation. 2Na + Cl₂ → 2NaCl. step 1: calculate the moles of Na. moles = mass/molar mass. From periodic table the molar mass of Na = 23 g/mol. moles = 115 g/23 g / mol = 5 moles. Step 2 : use the mole ratio to determine the moles of NaCl. Na:NaCl is 2:2 = 1:1 therefore the moles of NaCl is also = 5 moles.

Explanation:

We know sodium is a very active metal and chlorine is also a very reactive non-metal. Usually, metals like to eliminate electrons and non-metals such as halogens like to accept electrons. Sodium readily eliminate its last shell electrons become Na+ cation and chlorine accepts that electron to form Cl-anion.

Answer:

Electrostatic repulsion, strong nuclear force

Explanation:

The nucleus consists of protons and neutrons. protons are positively charged while neutrons possess no charge.

Since protons are positively charged, they repel each other strongly (like charges repel). This strong repulsion of like charges makes the nucleus somewhat unstable leading to spontaneous fission of heavy nuclei.

However, an opposing force called nuclear attractive force tends to hold the nucleons together. This attraction occurs when two nucleons are bonded by a particle called a π meson.

Hence, the two forces that act in the nucleus to create a  'nuclear tug-of-war' are electrostatic repulsion and a strong nuclear force.
