Answer:
Here are three types of probes that land on space physically. Interplantery, orbiters, and landers.
Explanation:
These are the ones that collect data and other stuff from space.
Answer:
22.5
Explanation:
all you have to do is take the number of moles of al and multiply them by sulfuric acids mole ratio as given in the equation (3), then divide by aluminums mole ratio number (2). then you will have moles of sulfuric acid.
*note: this only works if you are going moles to moles, if you are converting to anything else, this will NOT work*
if you have any questions leave them in the comments and i will try to answer them, if this helped, pls give a brainly
Here Is A Sentence You Could Possibly Use:
"The most common usage of non-contact force is weight."
Hope This Helps!
BTW, You May Want A Second Opinion Just In Case! :)
Answer is: Zn + Cu2+ → Zn2+ + Cu.
In this chemical reaction, there is transfer of electrons from zinc (Zn) to copper (Cu). Zinc change oxidation number from 0 to +2 (lost electrons) and copper change oxidation number from +2 to 0 (gain electrons).
Oxidation half reaction: Zn⁰ → Zn²⁺ + 2e⁻.
Reduction half reaction: Cu²⁺ + 2e⁻ → Cu⁰.
In other chemical reactions, there is no change of oxidation number of elements.
Answer:
1.21 g of Tris
Explanation:
Our solution if made of a solute named Tris
Molecular weight of Tris is 121 g/mol
[Tris] = 100 mM
This is the concentration of solution:
(100 mmoles of Tris in 1 mL of solution) . 1000
Notice that mM = M . 1000 We convert from mM to M
100 mM . 1 M / 1000 mM = 0.1 M
M = molarity (moles of solute in 1 L of solution, or mmoles of solute in 1 mL of solution). Let's determine the mmoles of Tris
0.1 M = mmoles of Tris / 100 mL
mmoles of Tris = 100 mL . 0.1 M → 10 mmoles
We convert mmoles to moles → 10 mmol . 1mol / 1000mmoles = 0.010 mol
And now we determine the mass of solute, by molecular weight
0.010 mol . 121 g /mol = 1.21 g
