Explanation:

have a good day btw i had this question before:D

Answer:

6.61 L

Explanation:

M1 = 6.25

V1 = 15.58

M2 = 14.73

M1V1 = M2V2

(6.25)(15.58) = (14.73)V2

V2 = 6.61 L

Answer:

1.875 dm^3

Explanation:

M = moles of solute ÷ volume of solution

M =11.25 x 6

  = 1.875 dm^3

2L is the correct answer .

HOW TO CALCULATE ??

                      Molarity (M)            = 6

     On puting values and solving we get , V = 1.875 L ≈ 2L

#SPJ2

Answer:

2.28 M

Explanation:

Using the formula as follows;

C1V1 = C2V2

Where;

C1 = initial concentration (M)

C2 = final concentration (M)

V1 = initial volume (L)

V2 = final volume (L)

According to the information given in this question;

C1 = 0.95M

C2 = ?

V1 = 0.60L

V2 = 0.25L

Using C1V1 = C2V2

0.95 × 0.60 = C2 × 0.25

0.57 = 0.25 C2

C2 = 0.57 ÷ 0.25

C2 = 2.28 M

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

Explanation:

I believe it's an endothermic but I'm not all too sure

Answer:

Pottasium nitrate is highly exothermic!However the dissolution of sodium nitrate in water is endothermic. Heat is absorbed during process.

Answer:process of cellular respiration allows plants to break down glucose into ATP. ... Although plants use photosynthesis to produce glucose, they use cellular respiration to release energy from the glucose.

Explanation:

Answer:

Explanation:

Thermal Power Plants generate electricity by converting heat into electricity, essentially by burning a fuel. ... A coal power plant works in much the same way, but instead of a nuclear reactor heating water to make steam, the heat from the burning coal powers a steam turbine

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.

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
