1,000 x 9.8 = 9800 Newtons
hope this helps
In chemistry, the molar mass M is a physical property defined as the mass of a given substance (chemical element or chemical compound) divided by its amount of substance. The base SI unit for molar mass is kg/mol. However, for historical reasons, molar masses are almost always expressed in g/mol.
Hope this helped!
Good luck :p

Answer:
AB
Explanation:
When combining two elements in different groups, you would just put them together unless you have two or more of each element
Answer:
The reducing agent is Zn.
Explanation:
Let's consider the reaction between zinc and hydrochloric acid.
Zn(s) + 2 HCl(aq) ⇄ ZnCl₂(aq) + H₂(g)
This is a redox reaction, which can be divided in 2 half-reactions: reduction and oxidation.
In the reduction, H⁺ gains electrons and it is considered the oxidizing agent.
2H⁺ + 2 e⁻ ⇒ H₂
In the oxidation, Zn loses electrons and it is considered the reducing agent.
Zn ⇒ Zn²⁺ + 2 e⁻
Answer:
You multiply the 3 numbers together to get your volume, in this case it would be 4058.488 cm^3 (cm cubed)
so
V: 4058.488cm^3 ( round up to 4058.5 for convenience)
M: 27579
D: ?
So we divide mass by the volume to get density, which is
27579 / 4058.5 = ~6.79536 (can round up to 7 or 6.8)
This graph can help a lot, so maybe try and memorize it, hope I helped.
