D
Larger surface area speeds up reactions 
Rust is an oxide so more oxygen should speed up rate of rust
Temperature also speeds up reactions

+ The humidity affects it aswell

To what volume should you dilute 50.0 ml of 12 m hno3 solution to obtain a 0.100 m hno3 solution?
bearhunter [10]

Answer:

The answer is "6L"

Explanation:

Formula:

\bold{C_1 \times V_1 = C_2 \times V_2 }\\\\V_2= \frac{C_1\times V_1}{C_2}

Values:

\to C_1= 12 \ m\\\to V_1= 50 \ ml\\\to C_2= 0.100 \ m\\\\\\V_2= \frac{12 \times 50 }{0.100}

   = \frac{12 \times 50 }{0.100}\\\\= \frac{12 \times 50 \times 1000}{100}\\\\= \frac{600 \times 1000}{100}\\\\= 600 \times 10\\\\=6000 \ ml\\= 6 \ L

(GIVING BRAINLYIST) Which environment has low temperatures and low humidity?
Greeley [361]

Answer:

The answer would be tundra.

A rain forest has a lot of humidity because it rains a lot otherwise it wouldn't be called a rain forest.

Grassland has a somewhat high temperature and average humidity enough to keep it green and grassy hence grasslands.

A wetland has a lot of water but low temperatures. Still, humidity is water so wetlands aren't it.

Explanation:

Hope this helped.

A brainliest is always appreciated.

A positively charged substance is brought near the ion. What will most likely happen and why
d1i1m1o1n [39]

<u>Answer:</u> It repels positive ion and attracts negative ion.

<u>Explanation:</u>

There are 2 types of ions:

1. Cations: These ions are positively charged ions which are formed when a substance looses electrons.

2. Anions: These ions are negatively charged ions which are formed when a substance gains electrons.

It is known that, like charges repel each other and unlike charges attract each other.

As, it is given that the substance is positively charged, so it will attract anion and repel cation.
