0.05

Explanation:

We find the rate of the chess

Sarah is 2.5/10

Arun is 1.6/8

We will get

0.25 for Sarah

0.20 for Arun

We subtract the two

0.25 - 0.20, we then get 0.05

Sarah has 0.05 more cheese in one serving than Arun

Answer:

4. all the above

Explanation:

It's all of the above because Thermal energy has all three. An example is like a pot of water on the stove boiling.  Radiation is coming off of the eye of the stove. Conduction occurs when heat transfers from hot to cold ( like the handle of the pot). Convection occurs in the boiling of the water by rotating causing the heat to rise.

Along the coast, its always colder near water

Answer:

well I dont know much about it but....

I think the soul if nature is kind if like a goddess which provides us the reason to live and the reason to die.

I guess thats it :/

Answer:

The human soul is naturally and essentially immortal; it is uncreated and eternal. The soul passes from one body to another through a series of many incarnations. After paying off its sin (karmic debt), the soul is liberated from somatic existence and lives in a totally blissful state.

Answer:

The new pressure of the gas is 395.5mmHg

Explanation:

The pressure of a gas is inversely proportional to its concentration (Boyle's law). The equation that explain this law is:

P₁V₁ = P₂V₂

Where P is pressure

And V is volume of 1, initial state and 2, final state of the gas

Initial state:

791mmHg; 0.500L.

Final state:

1.00L

Replacing:

791mmHg* 0.500L = P₂*1.00L

P₂ = 395.5mmHg

Answer:

Fnet = 13920 Newtons

Explanation:

Net force can be defined as the vector sum of all the forces acting on a body or an object i.e the sum of all forces acting simultaneously on a body or an object.

Mathematically, net force is given by the formula;

[tex] Fnet = Fapp + Fg[/tex]

Where;

Given the following data;

Mass, m = 800 kg

Acceleration, a = 7.6m/s²

To find the applied force;

[tex] Fapp = ma[/tex]

Substituting into the equation, we have;

[tex] Fapp = 800 * 7.6[/tex]

Fapp = 6080N

To find the gravitational force;

We know that acceleration due to gravity, g = 9.8m/s²

[tex] Fg = mg[/tex]

Substituting into the equation;

[tex] Fg = 800 * 9.8[/tex]

Fg = 7840N

To find the net force;

[tex] Fnet = Fapp + Fg[/tex]

Substituting into the equation, we have;

[tex] Fnet = 6080N + 7840N[/tex]

Fnet = 13920 Newton.

Therefore, the net force experienced is 13920 Newton.

Balancing an equation

Explanation:

These steps describes the processes which are involved in balancing a chemical equation.

In balancing the a chemical equation, the law of conservation of mass is strictly adhered to. It suggests that in a chemical reaction, atoms are neither created nor destroyed, but they combine with one another.

Answer:

balancing

Answer:

No, it is not

Explanation:

The reason for this answer is below

To conduct an experiment/investigation that involves the use of specific amounts of carbon dioxide and water by plants, one needs a controlled environment where the amount of carbon dioxide and water made available to the plant can be monitored and regulated as desired by the experimental design. The neighbor's backyard cannot provide this controlled environment and thus it is a bad idea.

Note that the neighbor's backyard cannot provide the controlled environment because the amount of carbon dioxide the plants will be exposed to there cannot be regulated as this is the carbon dioxide from the atmosphere and also the plants could get additional water from midnight dew which cannot be regulated also.

It is a good idea to use backyard garden to conduct an investigation of

how tomato plants use specific amounts of carbon dioxide and water to

grow at a certain rate.

To obtain an accurate result, experiments should be done in an

environment  which is similar to those in which plants are exposed to during

photosynthetic reactions.

The use of the backyard garden will have different factors such as

atmospheric pressure, sunlight, precipitation which the plants are exposed to

in its normal environment which is why it is a good idea.

Answer:

Chemical equation: AgNo3 + LiBr = AgBr + LiNO3

Explanation:

Answer:

Chemical equation: AgNO3 + LiBr -> AgBr + LiNO3

Complete Ionic equation: Ag + NO3 + Li + Br -> AgBr + Li + NO3

Net Ionic equation: Ag + Br -> AgBr

Explanation:

You start out with the chemical equation. We know that to get to the complete ionic equation we have to follow the solubility guidelines for common ionic compounds. In there, we can see that NO3 is soluble with no exceptions, which means every NO3 in this equation should be separated from the compound (this brings us to Ag + NO3 + LiBr -> AgBr + Li + NO3). Next we should separate Br, but be careufl because in the solubility guidelines it states that an exception to this being soluble would be if Br was next to Ag, Hg, and Pb. Since our second Br is next to an Ag, our equation will look like Ag + NO3 + Li + Br -> AgBr + Li + NO3. To find the net ionic equation all we're going to need to find are the substances that cancel each other out on both sides of the equation (aka the spectator ions). Our spectator ions in this case are Li and NO3. After we cancel those out, our net ionic equation is Ag + Br -> AgBr.

Answer: B

Explanation:

The observations about the fizzing mixture provide evidence of a chemical reaction is A substance escaped from the beaker in the form of a gas. The correct option is B.

A chemical reaction is a process of forming a compound from two substances. The substance that reacts to create a compound is called a reactant, and the compound that is formed after the reaction is called a product.

In a beaker, a chemist mixed hydrochloric acid with a sample of baking soda. The two chemicals together instantly started to bubble and fizz. Fizz is the bubbles that are made in the reaction, they are realized in the environment. Thus, they have escaped from the beaker.

Thus, the correct option is B. A substance escaped from the beaker in the form of a gas.

Periodic table

Explanation:

Answer:

Explanation:

volume of spherical ball = 4/3 x π R³

= 4 x 3.14 x .5³ / 3

= .5233 cm³ or ml.

mass = 2 g

density = mass / volume

= 2 / .5233

= 3.8 g / ml .

So its density is more than that of water , hence it will sink into water .

General Formulas and Concepts:

Chem

Explanation:

Sn has 2 general forms in charges: Sn²⁺ and Sn⁴⁺ as it is a Post-Transition metal.

Nitrate, NO₃⁻, has a 1 minus charge.

To balance out these charges from the given compound, we know that there are going to be 4 nitrates to balance out a charge. +4 and -4 equals 0, so the charge of Sn would be +4.

Therefore, our compound name would be Metal (Oxidation Number) polyatomic ion:

Answer:

Thomson's plum pudding model of the atom had negatively-charged electrons embedded within a positively-charged "soup." Rutherford's gold foil experiment showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus. Based on these results, Rutherford proposed the nuclear model of the atom.

Answer:

9.03 x 10²³atoms

Explanation:

Given parameters:

Number of moles of CO₂  = 1.5mol

Unknown:

Number of atoms  = ?

Solution:

In a mole of a substance, we have the Avogadro's number of particles which is 6.02 x 10²³atoms.

  Using this number, we can determine the amount of atoms in any substance.

If;

       1 mole of CO₂ contains 6.02 x 10²³ atoms;

     1.5mole of CO₂ will contain 1.5 x 6.02 x 10²³ atoms

                                                = 9.03 x 10²³atoms
