Would convection occur if Earth's mantle were a box 30 km on a side?​

Answers

Answer 1

Answer:

No.

Explanation:

No, convection does not occur if Earth's mantle were a box 30 km on a side because convection needs medium for the movement of heat energy from one place to another. Convection and conduction are two processes which needs medium for its movement while radiation does not need any medium for its movement. If there is a empty space present between two substances so convection does not occur.

Calcium carbide ( CaC2) reacts with water to produce acetylene (C2H2) as shown in the unbalanced reaction below: CaC2(s)+H2O(g)->Ca(OH)2(s)+C2H2(g). How many grams of H2O are required to completely react with 82.4g of CaC2

Answers

Answer:
46.3g H2O

Explanation:
start by balancing it: CaC2(s) + 2H2O(g) -> Ca(OH)2(s) + C2H2(g)

then use factor label method to solve

82.4g CaC2 x (1 mol CaC2/64.10g CaC2) x (2 mol H2O/1 mol CaC2) x (18.016g H2O/1 mol H20) = 46.3g H2O

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.

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.

A given volume of methane diffuses in 20 seconds How long will it take the
same volume of sulphur (IV) oxide to
diffuse under the same condition
(Methane = 16, Sulphur (IV) oxide=64)​

Answers

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

Diffrentiate between atoms and ions.

Answers

Hello. What is an Atom?
The smallest unit of matter. It is indivisible and consists of neutrons, electrons and protons. Atoms can take part in chemical reactions. Combination of atoms together forms molecule. Always the number of protons and electrons are equal. Independent life may or may not be feasible within a solution. Nucleus of the atom is formed by protons and neutrons. Surrounding the nucleus are the electrons.

What is an Ion?
Atoms where the electrons and protons are not equal are called ions. Ions are charged particles. They can be either positively charged ions or negatively charged ions. If an atom is charged electrically it is considered an ion. If an atom contains maximum number of electrons than protons, then it is called anion. If an atom contains maximum number of protons than electrons, then it is called cation. Independent existence in a solution. When an atom gains or loses electrons, ion is formed. Hope it helps

An experiment was conducted to find the mass of one mole of carbon atoms. The results of the experiment showed that a mole of carbon atoms had a mass of 15.78 g. The accepted value of a mole of carbon atoms is 16.00 grams. What is the percent error in this experiment?

Answers

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%
