Explanation:

To find the number of atoms of titanium , given it's number of moles we use the formula

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question

n = 0.075 mol

We have

N = 0.075 × 6.02 × 10²³

We have the final answer as

Hope this helps you

Answer:

There are 3 non-metals in benzoic acid.

Explanation:

They are Hydrogen, Oxygen, and Carbon.

Answer:

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

From the question

density = 0.79 g/mL

1 L = 1000 mL

6.5 L = 6500 mL

We have

mass = 0.79 × 6500

We have the final answer as

Hope this helps you

Answer:

The density of ice ice is lesser than that of water that's why ice floats on water. So hence, the answer is C

Answer:

Less than that of water

Explanation:

This explains why icebergs float on water. If it was greater than that of water icebergs would sink.

Answer:

C. An intitial velocity that is faster than a final velocity.

Explanation:

taking the test rn but it makes sense because you'd have to slow down to get  a lesser final velocity.

Answer:

C

Explanation:

Answer:

You need the Delta H fusion for water. Multiply that by 50 grams. Then multiply 50 g x 4.184 x 65 to get joules to raise water to 65 degrees. Add these values together to get total joules.

one molecule of water contains two atoms of hydrogen and one atom of oxygen, the atomicity of water is three.

Answer:

A gas is evolved

The ingredients can not be recovered

Explanation:

A chemical change is one in which a new substance is formed and it is not easily reversible.

One major ingredient used in cake baking is the baking powder or baking soda.

Baking a cake can be viewed as a chemical change. This is because, when the baking powder or soda is added in the presence of yeast, carbon dioxide gas is evolved as tiny bubbles of gas which makes the cake light and fluffy. Heat is equally given off in the process. The baking powder and other cake ingredients can not be recovered, hence, we can conclusively assert that a chemical change has taken place.

Answer:

The study population is the subset of the target population available for study (e.g. schizophrenics in the researcher's town). The study sample is the sample chosen from the study population.

Explanation:

In research terminology the Population can be explain as a comprehensive group of individuals, institutions, objects and so forth with have a common characteristics that are the interest of a researcher. Any value which is identified or measured from the characteristics of entire population can be called as Parameter.

balanced;

Explanation:

CaO + 3C → CaC2 + CO  //all elements are balanced

Na + H2O → 2NaOH + H2  //Na is not balanced on the left

4Fe + O2 → 2Fe2O3  //O is not balanced on the left

2Mg + O2 → 2MgO //left is equal to right, balanced

Answer:

1 pm = 10^-12 m = 10^-10 cm = 10^-9 mm

1.04 x 10^-3 pm = 1.04 x 10^-3 x 10^-9

= 1.04 x 10^-12 mm.

Answer:

4.9 cm³

Explanation:

Given data:

Mass value = 8.3 kg

Density = 1.7 kg/cm³

Volume = ?

Solution;

In given question from the units we got to know that the mass and density value is given and we have to calculate the volume.

Thus, we will apply density formula.

Density = mass/ volume

d = m/v

1.7 kg/cm³ = 8.3 kg/ v

v =  8.3 kg/ 1.7 kg/cm³

v = 4.9 cm³

Thus, the volume is 4.9 cm³.

Explanation:

i has picture here of correctness.

Given parameters:

Distance of ATV  = 60miles

Time = 2hrs

Unknown:

Speed  = ?

Solution:

Speed is a scalar quantity. It has magnitude but no direction. Mathematically, speed is distance divided by time.

                      Speed  = [tex]\frac{distance}{time}[/tex]

 Input the parameters;

              Speed  = [tex]\frac{60}{2}[/tex]  = 30miles/hr

The speed of the ATV is 30miles/hr
