Answer: It loses electrons to another element.
Explanation:- Oxidation is the process in which an element loses electrons and there is an increase in the oxidation state. On losing electrons it combines with a electronegative element such as oxygen, sulphur or nitrogen etc.
Reduction is the process in which an element gains electrons and there is a decrease in the oxidation state.
Answer:
The answer is
<h2>59.6 g </h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
Density of aluminum = 2.00 g/mL
volume = 29.8 mL
The mass is
mass = 2 × 29.8
We have the final answer as
<h3>59.6 g</h3>
Hope this helps you
Answer:
<h2>Actin and myosin.</h2>
Explanation:
The cells that allow your bones to move, the movement of thick (myosin) and thin (actin) filaments during contraction
.
During a contraction thick and thin filaments do not shorten but increase their overlap of each other.
Thin filaments slide past thick filaments extending more deeply into the A band.
The I bands and H bands decrease in lenght as Z discs are come closer together
.
Sarcomere represents area between two Z disc, so the sarcomere gets smaller during a contraction
.
Answer:
acid +alkaline =salt and water
Explanation:
if an acid reacts with an alkaline they form salt and water
Answer:
d) V = 91.3 L
Explanation:
Given data:
Volume of nitrogen = ?
Temperature = standard = 273.15 K
Pressure = standard = 1 atm
Number of atoms of nitrogen = 2.454×10²⁴ atoms
Solution:
First of all we will calculate the number of moles of nitrogen by using Avogadro number.
1 mole = 6.022×10²³ atoms
2.454×10²⁴ atoms × 1 mol / 6.022×10²³ atoms
0.407×10¹ mol
4.07 mol
Volume of nitrogen:
PV = nRT
1 atm × V = 4.07 mol ×0.0821 atm.L /mol.K ×273.15 K
V = 91.3 atm.L /1 atm
V = 91.3 L
