Explanation:

Answer:

7amu

Explanation:

Atoms are composed of three particles.  The proton, neutron, and electron.  

The mass of the atom in amu is just the number of protons and neutrons in the nucleolus since they both have a mass of about 1 amu.  Electrons are not counted since they have an incredibly small mass that ultimately does not matter.  

This atom has 3 protons (positively charged particle) and 4 neutrons (particle with no charge) which together gives a mass of 7 amu.

Answer:

Explanation: A more reactive metal will displace a less reactive metal from a compound. The thermite reaction is a good example of this. It is used to produce white hot molten (liquid) iron in remote locations for welding. A lot of heat is needed to start the reaction, but then it releases an incredible amount of heat, enough to melt the iron.

aluminium + iron(III) oxide → iron + aluminium oxide

2Al + Fe2O3 → 2Fe + Al2O3

Because aluminium is more reactive than iron, it displaces iron from iron(III) oxide. The aluminium removes oxygen from the iron(III) oxide:

Answer:

Displacement reactions involve a metal and a compound of a different metal. In a displacement reaction:

Explanation:

a more reactive metal will displace a less reactive metal from its compounds

Displacement reactions are easily seen when a salt of the less reactive metal is in the solution. During the reaction:

the more reactive metal gradually disappears as it forms a solution

the less reactive metal coats the surface of the more reactive metal

For example, magnesium is more reactive than copper. When a piece of magnesium is dipped into blue copper sulfate solution:

the blue colour fades as colourless magnesium sulfate solution forms

brown copper coats the surface of the magnesium

Answer: The final volume of the balloon is 335.6 L

Explanation:

To calculate the final volume of the balloon, we use the equation given by combined gas law:

[tex]\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}[/tex]

where,

[tex]P_1[/tex] = Initial pressure = 1.2 atm

[tex]P_2[/tex] = Final pressure = [tex]3.00\times 10^{-3}[/tex] atm

[tex]V_1[/tex] = Initial volume = 1.00 L

[tex]V_2[/tex] = Final volume = ?

[tex]T_1[/tex] = Initial temperature = [tex]25^oC=[25+273]=298K[/tex]

[tex]T_2[/tex] = Final temperature = [tex]-23^oC=[-23+273]=250K[/tex]

Putting values in above equation, we get:

[tex]\frac{1.2atm\times 1.00L}{298K}=\frac{3.00\times 10^{-3}atm\times V_2}{250K}\\\\V_2=\frac{1.2\times 1.00\times 250}{298\times 3.00\times 10^{-3}}\\\\V_2=335.6L[/tex]

Hence, the final volume of the balloon is 335.6 L

Answer:

The specific heat of magnesium is 1.02 J/g.K

Explanation:

To calculate the energy involved in the heating of the metal (magnesium), we use the following expression:

energy = mass x Cp x ΔT

We have the following data:

mass = 2.00 kg x 1000 g/1.00 kg = 2000 g

energy = 8160 J

ΔT = 4 K

Thus, we can calculate the specific heat of magnesium (Cp) in J/g.K as follows:

⇒ Cp = energy/(mass x ΔT) = 8160 J/(2000 g x 4K) = 1.02 J/g.K

Explanation:

The rotation of earth happens about once every 24 hours.

Answer:

object's inertial property

Explanation:

The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it. The pull of gravity on the earth gives an object a downward acceleration of about 9.8 m/s2.

Answer:

A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and formulae, wherein the reactant entities are given on the left-hand side and the product entities on the right-hand side.

Explanation:

Answer:

Even though plants are rooted in the ground, they still move, exert force, and do work.

Plant cells have very strong cell walls that allow pressure to build up inside of the cell as water is absorbed. This pressure is called turgor.

When turgor pressure is high enough in a cell, the cell walls become firm and as a result, the cell becomes rigid and the plant is able to stand tall and straight.

When a plant does not get enough water, the turgor pressure inside of the cells decreases. A decrease in pressure pushing against the cell wall causes the cells to lose their shape and shrink. This causes the plant to begin to droop or wilt.

When the wilted plant gets enough water, the cells will become rigid again, and the plant will stand firm and straight once again.

Explanation:

-Synthesis reactions are reactions that appear when two distinct atoms or molecules engage to structure a specific molecule or compound. Most of the time, when a synthesis response occurs, electricity is launched and the response is exothermic. However, an endothermic consequence is additionally possible.

-A decomposition response starts offevolved from a single substance and produces extra than one substance; that is, it decomposes. One substance as a reactant and greater than one substance as the merchandise is the key attribute of a decomposition reaction. For example, in the decomposition of sodium hydrogen carbonate (also recognized as sodium bicarbonate)

-A single-replacement response (sometimes referred to as a single-displacement reaction) is a chemical response in which one aspect is substituted for every other factor in a compound, producing a new aspect and a new compound as merchandise

-A double-replacement response (sometimes referred to as a double-displacement reaction) takes place when components of two ionic compounds are exchanged, making two new compounds. A attribute of a double-replacement equation is that there are two compounds as reactants and two distinctive compounds as product

-A combustion response happens when a reactant combines with oxygen, many instances from the atmosphere, to produce oxides of all different factors as products; any nitrogen in the reactant is transformed to elemental nitrogen, N2. Many reactants, referred to as fuels, incorporate normally carbon and hydrogen atoms, reacting with oxygen to produce CO2 and H2O

A chemical reaction may involve one or more reactants to yiled one or more products.

Below we are going to discuss the types of reaction under the following headings;

Synthesis reaction - This is a reaction in which two or more substances come together to yiled a single product.

Decomposition reaction - This involves the breakdown of a substance into new substances.

Single Replacement Reaction- This is a type of reaction in which an atoms replaces another in a compound.

Double Replacement Reaction - This is a reaction in which cations exchange anion partners in a reaction

Combustion - This is a reaction in which a substance is burnt in oxygen.
