Answer:
Science is really reliable because there is research and math and brains. Actual science are results from experiments, so it's mainly always correct.
Explanation:
Microwaves are one type of electromagnetic radiation. compared to all other types of electromagnetic radiation, radio waves have the lowest frequency.<span> Radiant energy is energy that travels by radiation. an example of this is light. Yes microwaves are a type of infrared rays .</span>
<span>Given mass: 3.810 g of h2o and 13.96 g of co2.
Mass of CO2 : 13.96 g
moles of CO2 : 0.317 moles / 44.0098
moles of C : 0.317 moles
Mass of water = 3.81 g
moles of water = 0.212 moles / 18.015
moles of H = 0.423 moles X2
Hence the molar ratio C : H is 0.317 : 0.423
= 1.000 : 1.334
Multiplying by 3 on both ratios we get: 3.000 : 4.003
Therefore the empirical formula is C3H4</span>
Answer:
C, increases/decreases
Explanation:
As you move down a group on the periodic table, the electronegativity of an element decreases because the increased number of energy levels puts the outer electrons very far away from the pull of the nucleus.
Answer:
The ratio of an object's mass to its volume is called density of an object
Explanation:
Density=mass/volume
