The factors are
temperature of the land
ripening of oranges
evaporation of water
humidity of the surrounding air

Only one is a chemical property which is

Answer: A. 1

Explanation:

A physical change is defined as a change in physical properties of a matter such as shape , size and its state ( Solid , liquid or gas ).

This process is a reversible process.

On the other hand a chemical change is defined as a change in chemical properties of a matter such that its composition gets changed . This process is irreversible.

Given Factors : temperature , ripening , evaporation , humidity

Here,

Physical changes are : temperature , evaporation , humidity because they are reversible, they do not form a new substance.

But ripening of oranges is an irreversible process because its a chemical change in it which makes fruit more sweeter and softer.

Hence, there is only 1 factor which is a chemical change.

zzz [600]

Answer:

The energy of atomic orbitals increases as the principal quantum number, n, increases. In any atom with two or more electrons, the repulsion between the electrons makes energies of subshells with different values of l differ so that the energy of the orbitals increases within a shell in the order s < p < d < f.

what two errors in the data will result if you raise the temperature of the melting point apparatus too quickly?

grandymaker [24]

The two errors in the data resulting from an experiment where the temperature is raised too quickly are: First, the melting point temperature may not be recorded correctly since it cannot be monitored closely if the heat supplied is too high.

What is the balanced form of the chemical equation shown below?

Serga [27]

Answer:

A; $1 C_{12}H_{22}O_{11} + 12 O_{2} - > 11H_2O +12CO_2$

Explanation:

The best way to start solving this problem is to start with the molecule with the most atoms. Since there are 12 carbons on the left, you need 12 on the right so 12 would need to be placed in front of carbon dioxide. Also you need 22 hydrogens and in each molecule of water, there are two hydrogen molecules so you need 11 molecules of water. After balancing you find that you need 24 oxygen on the left so you place the coeffecient 12 in front of the oxygen molecule.

Answer ASAP Please this is a timed test

DiKsa [7]

you want to design a faster car

because thats engineering

○○○

testing evaporation is not engineering

and making slime isnt either...

lets say it like this do you use a wrench for slime or evaporation?

nope but you do for cars
