Answer:

72 Newton

Explanation:

force=mass x acceleration due to gravity

Force applied on object is 72 Newton​

Given that;

mass of thing = 6 kg

Acceleration = 12 m/s²

Find:

Force applied on object

Computation:

Force = mass × acceleration

Force applied on object = 6 × 12

Force applied on object = 72 Newton​

Answer:

It represents the relationship between the distance travelled and time spent as constant or at a stop.

Explanation:

This is because as the line progresses, the time increases the distance should change as well my moving up or down, in a linear equation this relationship is constand but if the line is horizontal though, the distance is not changing despite time passing which means it has come to a stop.

Answer:

296

Explanation:

Tk = ºC + 273

Tk = 23 + 273

T = 296 K

Explanation:

Relative molecular mass of CH4 = 12 * 1 + 4 = 16

Relative molecular mass of SO2 = 32 + 10 *2 = 64

tSO2/tCH4 = √MSO2/MCH4

t/20 = √64/16 = √4

t/20 = 2

∴ t = 20 * 2 = 40sec

The given reaction can be balanced as follows: CaC2 + 2H2O → Ca (OH)2 + C2H2. Grams of water required to completely react with 82.4 g of CaC2 is 46.28 g.

What is a balanced reaction?

In balanced reaction, the number of each and every element on both side is balanced. In the given reaction to balance the number of H and O, add 2 to H₂O so that, all the species will be equal in number on both side.

Now, as per the balanced reaction, 2 moles of water is required to reacts with 1 mole of CaC2.

Mass of one mole of water = 18 g/mol.

                                   2 mole = 36 g

Mass of one mole of CaC2 = 64.09 g/mol

Thus 36 g of water is required to react with 64.09 grams of calcium carbide. Mass of water required to react with 82.4 g of calcium carbide is calculated as follows:

Mass of water = (36 g×82.4 g)/64.09 g = 46.28 g

Hence, 46.28 grams of water is required to completely react with 82.4 g of calcium carbide.

Dihydrogen Dioxide

The name of binary molecule H₂O₂ is also known as hydrogen peroxide and is a popular disinfectant for cuts or scrapes is dihydrogen dioxide. The correct option is A.

Dihydrogen dioxide is the substance of water with extra oxygen molecules. In the dihydrogen monoxide parody, water is referred to by a strange scientific term, most frequently "dihydrogen monoxide,". It is a poisonous gas, and it is leading to the death of many people in America. It is known as DHMO.

Some of its characteristics are listed in an especially ominous manner, such as speeding up corrosion and inducing asphyxia. This substance, commonly referred to as hydrogen peroxide, is used frequently as a disinfectant for cuts and scrapes.

Thus, the correct option is A. Dihydrogen dioxide.

Answer:

A. 8.8 g.

B. 5.3 g.

C. 449 g.

Explanation:

A. Determination of the mass of CO2.

Mole of CO2 = 0.2 mole

Molar mass of CO2 = 12 + (2×16)

= 12 + 32

= 44 g/mol

Mass of CO2 =?

Mole = mass /Molar mass

0.2 = mass of CO2 /44

Cross multiply

Mass of CO2 = 0.2 × 44

Mass of CO2 = 8.8 g

B. Determination of the mass of Na2CO3.

Mole of Na2CO3 = 0.05 mole

Molar mass of Na2CO3 = (2×23) + 12 + (3×16)

= 46 + 12 + 48

= 106 g/mol

Mass of Na2CO3 =?

Mole = mass /Molar mass

0.05 = mass of Na2CO3 /106

Cross multiply

Mass of Na2CO3 = 0.05 × 106

Mass of Na2CO3 = 5.3 g

C. Determination of the mass of Fe(OH)2.

Mole of Fe(OH)2 = 5 moles

Molar mass of Fe(OH)2 = 55.8 + 2(16 + 1)

= 55.8 + 2(17)

= 55.8 + 34

= 89.8 g/mol

Mass of Fe(OH)2 =?

Mole = mass /Molar mass

5 = mass of Fe(OH)2/89.8

Cross multiply

Mass of Fe(OH)2 = 5 × 89.9

Mass of Fe(OH)2 = 449 g.

Answer:

1.375%

Explanation:

Percent Error = measured value - accepted value/ accepted value x 100

Measured Value: 15.78

Accepted Value: 16.00

Work:

[tex]\frac{15.78-16.00}{16.00}[/tex] * 100

[tex]\frac{-.22}{16}[/tex] * 100 = -1.375

You cannot have a negative percentage. Therefore the answer is 1.375%
