I think it is c but I’m not sure
The IUPAC says that elements have to be named after one of five things: a scientist, a place, a mineral or substance, a descriptor of the element, or a mythological reference. Of the new elements, three are named after places and one is named after a person No-one has yet named an element after themselves but many elements are named in tribute to important scientists
(you can cut some stuff out)
Answer:
The ratio is 2:1, that is 2mol C / 1mol O2
Explanation:
First check to see if the equation is balanced. It is so now let's find the ratio.
The ratio is the stoichiomeric coefficient of the element or compound.
Carbon : Oxygen
2C : 1 O2 , so 2:1 ..
Answer:
epithelial tissue, connective tissue, muscle tissue, and nervous tissue.
I think its right
brainiest pls
Explanation:
The number of ml of hcl required to react with Zn is calculated as follows
step one: calculate the number of Zn moles
that is mass/ molar mass of Zn
7.65 g/65.38 g /mol= 0.117 moles
step two : write the reacting equation
Zn + 2 HCl ---> ZnCl2 + H2
from the equation above the reacting ratio between ZN to HCl is 1:2
therefore the moles of HCL = 2 x 0.117moles = 0.234 moles
volume of Hcl= moles of HCl / molarity of Hcl
that is 0.234 /6=0.039 L , multiply by 1000 to convert to Ml since molarity is the concentration in litres
0.039 x1000= 39ML
