Why is the Northern Hemisphere warmer when tilted to the sun?

Chemistry
1 answer:
AnnZ [28]2 years ago
3 0

Answer:

The Sun gives off UV radiation and heat waves, when tilted closer, it is closer to that UV radiation and heat waves.

For example, if you put a heat lamp closer to a rock the rock would get warmer, if you put it further away it would receive less heat therefore making less warmer.

C2H4O2 + NaC2H3O2 + H2O + CO2 list the reactants in this chemical reaction
lisabon 2012 [21]

Answer:

C₂H₄O₂ and NaC₂H₃O₂ are reactants.

Explanation:

Word equation:

Acetic acid + sodium acetate  → sodium diacetate

Chemical equation:

C₂H₄O₂ + NaC₂H₃O₂  →  C₄H₇NaO₄

This is a synthesis reaction in which simple reactants combine to form complex product.

This is also balanced chemical equation because there are equal number of atoms of all elements on both side of equation. Thus it follow the law of conservation of mass.

Law of conservation of mass:

According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.

This law was given by french chemist  Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.

If a bottle of olive oil contains 1.4 kg of olive oil, what is the volume, in milliliters ( mL ), of the olive oil?
Serhud [2]

We know that density of olive oil = 0.93 g/mL

Given that mass of olive oil = 1.4 kg or 1400 g because 1000 g = 1.0 kg

From the definition of density;

Volume = mass/ density

= 1400 g/ 0.93 g/mL

=1505 mL
