They produce oxygen and glucose.
Hope this helps :)
Solution :
It is given that :
The formula of the compound = 
And that 4.70 g of the sample contains 
mol of Br.
It means that :
1 mol of contains = 3 mol of Br
∴ 3 mol of 
contain in 1 mol of
mol of contains 
mol of
Thus the mol of = mol
The given mass is = 4.700 g
Therefore, the 
of 
= 298.4 g/mol
So of = of X + 3 x of Br
298.4 g/mol = of X + 3 x 79.90 g/mol
298.4 g/mol = of X + 239.7 g/mol
of X = 58.71 g/mol (since 1 amu = 1 g/mol)
Therefore the atomic mass of the unknown metal = 58.71 g/mol
So the unknown meta is Nickel.
Answer:
Filtration method
Explanation:
Filtration is a separation method used to separate out pure substances in mixtures comprised of particles some of which are large enough in size to be captured with a porous material. Particle size can vary considerably, given the type of mixture. For instance, a mixture of boiled pasta and water.
The interior of mars is rigid
Explanation:
To produce the magnetic field of the earth, the outer core is fluid and constantly moving.
- The outer core is made up of metals
- These metals are rich in iron and nickel and some other elements.
- During the early formation of the earth, these minerals differentiated into this layer of the earth based on their density.
- But the outer core region is molten and fluid.
- The movement of these materials is responsible for the production of the geo-magnetic field that makes the earth behave like a bar magnet.
Mars has no magnetic field and we can suggest that its interior is rigid and solid.
