Answer:
Earth; heat.
Explanation:
Radiation can be defined as the flow, transmission or emission of energy in the form of atomic and subatomic particles and waves through a material medium or space.
Solar radiation is a form of electromagnetic radiation emitted by the sun on the earth's surface as ultraviolet, infrared and visible light.
Hence, the sun radiates energy towards the earth surface and some of this radiant energy is in the form of heat. Radiation is generally considered to be the least important mode of the transportation of heat from one point to another in planet earth.

Explanation:
At what temperature would a 1.30 m NaCl solution freeze, given that the van't Hoff factor for NaCl is 1.9? Kf for water is 1.86 ∘C/m .
Answer:
-4.59°C
Explanation:
Let's see the formula for freezing point depression.
ΔT = Kf . m . i
ΔT = Freezing T° of pure solvent - Freezing T° of solution
Kf = Freezing constant. For water if 1.86°C/m
m = molality (moles of solute in 1kg of solvent)
i = Van't Hoff factor.
0°C - Freezing T° of solution = 1.86°C /m . 1.30m . 1.9
Freezing T° of solution = - (1.86°C /m . 1.30m . 1.9)
Freezing T° of solution = - (1.86°C/m . 1.30m . 1.9) → -4.59°C
NaCl → Na⁺ + Cl⁻

I am wondering how to find out the blood type of my grandson...my daughter is A+..father is in question...she is stressed to the max on the father of this baby boy.
Answer:
A person can identify their blood type at home using a rapid blood typing kit. Using the kit requires a person to pierce a finger with a needle. The kit comes with a card that contains chemicals known as reagents. These test for the presence of the antibodies and Rh factor.
Explanation:
Just like eye or hair color, our blood type is inherited from our parents. Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive. For example, if an O gene is paired with an A gene, the blood type will be A.

If 100 ml of a 0.5 M HCI Solution is diluted with water to 1000ml, what is the new concetration?
Answer:
[tex]0.05\ \text{M HCl}[/tex]
Explanation:
[tex]V_1[/tex] = Initial volume = 100 mL
[tex]V_2[/tex] = Final volume = 1000 mL
[tex]M_1[/tex] = Initial concentration = 0.5 M
[tex]M_2[/tex] = Final concentration
We have the relation
[tex]\dfrac{M_1}{M_2}=\dfrac{V_2}{V_1}\\\Rightarrow M_2=M_1\dfrac{V_1}{V_2}\\\Rightarrow M_2=0.5\times \dfrac{100}{1000}\\\Rightarrow M_2=0.05\ \text{M HCl}[/tex]
The new concentration is [tex]0.05\ \text{M HCl}[/tex].
How many grams of potassium chloride (KCl) can be produced from 180.6 g of chlorine (Cl2)?
Answer:
379.79 g of KCl
Explanation:
The balanced equation for the reaction is given below:
Cl₂ + 2KBr —> Br₂ + 2KCl
Next, we shall determine the mass of Cl₂ that reacted and the mass of KCl produced from the balanced equation. This can be obtained as follow:
Molar mass of Cl₂ = 70.90 g/mol
Mass of Cl₂ from the balanced equation = 1 × 70.90 = 70.90 g
Molar mass of KCl = 74.55 g/mol
Mass of KCl from the balanced equation = 2 × 74.55 = 149.1 g
SUMMARY:
From the balanced equation above,
70.90 g of Cl₂ reacted to produce 149.1 g of KCl.
Finally, we shall determine the mass of KCl produced by the reaction of 180.6 g of Cl₂. This can be obtained as follow:
From the balanced equation above,
70.90 g of Cl₂ reacted to produce 149.1 g of KCl.
Therefore, 180.6 g of Cl₂ will react to produce = (180.6 × 149.1)/70.90 = 379.79 g of KCl.
Thus, 379.79 g of KCl were obtained from the reaction.

How many moles of a gas would occupy 22.4 Liters at 273 K and 1 atm?
Read bottom comment
Answer:
The following relationship makes this possible: 1 mole of any gas at standard temperature and pressure (273 K and 1 atm) occupies a volume of 22.4 L.
Explanation:
1 mole of any gas would occupy 22.4L of gas at standard temperature and pressure (STP) i.e at 273K and 1 atm.
The STP conditions refer to the standard temperature and pressure. Pressure values at 1 atmosphere and temperature at 0 ° C (or 273 K) are used and are reference values for gases. And in these conditions 1 mole of any gas occupies an approximate volume of 22.4 liters.
An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of the gases:
P V = n R T

How many bases of RNA represent an amino acid?
Answer:
three bases
Genetic experiments showed that an amino acid is in fact encoded by a group of three bases, or codon.
Explanation:
Hope this helps
In the given question, three bases of RNA represent an amino acid.
RNA (ribonucleic acid) is a molecule that plays an important role in protein synthesis. It carries genetic information from DNA to ribosomes, where it is used to direct the assembly of amino acids into proteins.
The genetic code is the set of rules by which the sequence of nucleotides in DNA or RNA is translated into the sequence of amino acids in a protein. The code is based on the sequence of three nucleotides, known as a codon, which specifies a particular amino acid.There are 64 possible codons, but only 20 amino acids that are used to build proteins. This means that some amino acids are specified by more than one codon. For example, the amino acid leucine can be specified by six different codons: UUA, UUG, CUU, CUC, CUA, and CUG.Therefore, three RNA bases represent an amino acid.
