Answer:

Equation of Reaction

2AgNO3 + BaCl2 === 2AgCl + Ba(NO3)2

Molar Mass of AgNO3 = 170g/mol

Moles of reacting AgNO3 = 100g/170gmol-¹

=0.588moles of AgNO3

From the equation of reaction...2moles of AgNO3 reacts to Produce 2Moles of Silver Chloride

So Their ratio is 2:2.

This means that 0.588Moles of AgCl Will be produced too.

ANSWER...0.588MOLES OF AgCl WILL BE PRODUCED.

C₂H₄O

Explanation:

Empirical formulas show the simplest ratio of atoms in a compound in whole numbers.

We can think that all the atoms are divisible by 4.

As we need the lowest number for each subscript, empirical formula is:

C₂H₄O

We have divided, 8/4 for carbon, 16/4 for H and 4/4 for O.

Lithium Bromide: LiBr and Potassium chloride: KCl.

Explanation:

A substance that will conduct electricity when dissolved completely in water is known as an Electrolyte.

Now, electrolytes are usually salts that ionize completely in a solution unlike non - electrolytes that do not dissociate into ions in solution.

Looking at the options, the only ones that are Salts are Lithium Bromide: LiBr and Potassium chloride: KCl.

Thus, options

Lithium Bromide: LiBr and Potassium Chloride: KCI will conduct electricity

when dissolved in water.

Electrolytes are referred to as compounds which conduct electricity when

dissolved in water. A salt is a common example of a compound which

dissolves in water to  generate electricity which makes it an electrolyte.

In the options the salts present are Lithium Bromide and Potassium

Chloride which is why options B and D are the most appropriate choice.

C₄H₃N

Explanation:

To solve this question we must find the moles of each atom in order to find the empirical formula (Simplest ratio of atoms present in a molecule). With empirical formula and the molar mass of the compound we can find the molecular formula as follows:

Moles H:

91.5mg H * (1mmol / 1mg) =

91.5mmol H

Moles N:

424mg N * (1mmol / 14mg) =

30.286mmol N

The ratio of moles regard to moles N (The lower number of moles is:

H = 91.5mmolH / 30.286mmolN = 3.0

N = 30.286mmolN / 30.286mmolN = 1

empirical formula = CₓH₃N

The molar mass of this formula is:

12*x + 1*3 + 1*14 = 17g/mol

Solving for X:

12X + 17g/mol = 65g/mol

12X = 48g/mol

X = 4

The heating of the sodium acetate solution made it change from super-saturated to un-saturated. Yet now that it cooled back to room temperature Im sure it is saturated. it wasn't able to disolve the excess sodium acetate left over at room temperature and had to be heated so now that it is back to room temperature I Think it will not disolve the sodium acetate left in the solution until it is heated again.

Answer: single, normal weather event like a hurricane

Explanation:

Climate change is variation in the average weather conditions. This brings about a wetter, drier or warmer condition. Climate change is typically caused by human activities.

Some of the recent changes in global climate include prairies giving way to deserts in Africa and the American West, more and longer heat waves and coral reefs dying off.

It should be noted that a single, normal weather event like a hurricane isn't a result of climate change.

Answer:

3.12 x 25.6 = 79.9 g

Answer:

A) It's correctly written

B) 77%

C) 835 calories

Explanation:

A) From online sources, we have number of calories as follows;

Fats: 9 calories per gram

Protein; 4 calories per gram

Carbs; 4 calories per gram

Total calories for each;

Total fat = 3 × 9 = 27 calories

Total protein = 3 × 4 = 12 calories

Total carbs = 32 × 4 = 128 calories

(sugar and dietary Fibre are classified as carbohydrates and so total carbs takes care of their calories).

Thus, total number of calories per serving = 27 + 12 + 128 = 167 calories per serving which is same as what is given.

B) percent from carbohydrates per serving = total calories from carbs/total number of calories per serving × 100% = 128/167 × 100% ≈ 77%

C) One box contains 5 servings. Thus total number of calories per box = 167 × 5 = 835 calories

Option A is correct.

This is because atoms get compressed when the pressure increases and takes less space, on the other hand, the atoms get expanded when pressure decreases and hence take more space.

aluminium has bigger atomic size than chlorine

because atomic radii decreases across the period and increases down the group

this law would hold owing to the fact that chlorine and aluminum are on the same period

Answer:  Mafic rocks are dominated by plagioclase and pyroxene (even if you can't see them with the naked eye) and smaller amounts of olivine. Intermediate rocks are roughly even mixtures of felsic minerals (mainly plagioclase) and mafic minerals (mainly hornblende, pyroxene, and/or biotite). There is little or no quartz.

Answer:

39.2 g

Explanation:

2Ni₂O₃(s) ⟶ 4Ni(s) + 3O₂(g)

First we convert 55.3 g of Ni₂O₃ into moles, using its molar mass:

55.3 g ÷ 165.39 g/mol = 0.334 mol Ni₂O₃

Then we convert 0.334 Ni₂O₃ moles into Ni moles, using the stoichiometric coefficients of the balanced reaction:

0.334 mol Ni₂O₃ * [tex]\frac{4molNi}{2molNi_2O_3}[/tex] = 0.668 mol Ni

Finally we convert 0.668 Ni moles into grams, using its molar mass:

0.668 mol * 58.69 g/mol = 39.2 g

No of moles of NO = 824/30.01= 27.45 mole

Hence 27.5 moles of NO are formed!

The identity of the sample is copper. The correct option is  D. copper

To determine the identity of the sample, we will determine its specific heat, c.

From the formula

Q = mcΔT

Where Q is the quantity of heat

m is the mass

c is the specific heat of the substance

and ΔT is the change in temperature

From the given information

Q = 3080 J

m = 200 g

ΔT = T₂ - T₁ = 60°C - 20°C = 40°C

Putting the parameters into the formula, we get

3080 = 200 × c × 40

3080 = 8000c

∴ c = 3080 ÷ 8000

c = 0.385 J / g°C

From specific heat table, the substance that has a specific heat of 0.385 J / g°C is Copper.

Hence, the identity of the sample is copper. The correct option is  D. copper
