Answer:
oxygen, water and sugar are the out come of photosynthesis
Answer:
Na+, O, C, Na
(Na+ has more ionization energy and Na has less ionization energy)
Answer:
The answers to your questions are given below.
Explanation:
Data obtained from the question include:
Mass (M) = 420.0 g
Temperature change (ΔT) = 43.8 °C
Specific heat capacity (C) = 3.52 J/g °C
Heat needed (Q) =...?
The heat needed for the temperature change can be obtained by using the following formula:
Q = MCΔT
Where:
Q is the heat needed measured in joule (J).
M is the mass of substance measured in grams (g)
C is the specific heat capacity of the substance with unit J/g °C.
ΔT is the temperature change measured in degree celsius (°C).
Thus, we can calculate the heat needed to change the temperature as follow:
Q = MCΔT
Q = 420 x 3.52 x 43.8
Q = 64753.92 J
Therefore, the heat needed to cause the temperature change is 64753.92 J
The number of mole of solute particles are present in 1 mL (exact) of aqueous 0.0040 M Ba(OH)₂ is 0.000004 mole
<h3>What is molarity? </h3>
Molarity is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:
Molarity = mole / Volume
With the above formula, we can determine the number of mole present in the solution. Detail below:
<h3>How to determine the mole of the solute in the solution</h3>
- Volume of solution = 1 mL = 1 / 1000 = 0.001 L
- Molarity of solution = 0.004 M
- Mole of solute =?
Molarity = mole / Volume
Cross multiply
Mole = Molarity × volume
Mole of solute = 0.004 × 0.001
Mole of solute = 0.000004 mole
Thus, the mole of the solute in the solution is 0.000004 mole

It is in stratigraphy when you study rock strata ( makes sense) and it is paleontology when you study fossils
