Answer:
The question is not appropriate.The correct explanation is given below.
Explanation:
- The molecule of the oxygen cannot have the water molecule but the water molecule have the molecules of oxygen, having formula of H2O.
- A molecule of oxygen is made by combining more than one atom of oxygen forming a molecule as the atoms combines to form a molecule.
- Also, the presence of number of molecules of a particular element in a compound is fixed according to the law of definite proportion which tells that:
- The atoms of elements present in a compound are in a fix ratio by mass to be called the molecule of that particular compound.
- For example: The Formula of water is H2O having 2 atoms of hydrogen and one atom of oxygen forming a ratio of 2:1 to form ONE molecule of water. If this ratio is not maintained then we cannot call it a molecule of water.
To calculate the average atomic weight, each exact atomic weight is multiplied by its percent abundance, then add the results together and round off to an appropriate number of significant figures. So according to what’s given, the average atomic mass of elements M should be (23.9850 x 0.7899) + (24.9858 x 0.1000) + (25.9826 x 0.1101) = 24.30
Answer:
sulphuric acid and ammonium hydroxide
Explanation:
They are different types of batteries. there are zinc carbon batteries, alkaline batteries, lithium carbon batteries, lead-acid batteries.
lithium is used for high performance devices such as smartphones, digital cameras and even electric cars.A variety of substances are used in lithium batteries, but a common combination is a lithium cobalt oxide cathode and a carbon anode
lead-acid batteries: This is the chemistry used in a typical car battery. The electrodes are usually made of lead dioxide and metallic lead, while the electrolyte is a sulfuric acid solution.
zinc carbon batteries; The anode is zinc, the cathode is manganese dioxide, and the electrolyte is ammonium chloride or zinc chloride.
alkaline batteries;The cathode is composed of a manganese dioxide mixture, while the anode is a zinc powder. It gets its name from the potassium hydroxide electrolyte, which is an alkaline substance.
Answer:
B
Explanation:
A cation is a positively charged in. If an atom gives away an election, which is negatively charged, that would make it more positively charged, thus a cation.
The epidermis is a dermal tissue<span> that is usually a single layer of cells covering the younger parts of a plant. It secretes a waxy layer called the cuticle that inhibits water loss.</span>
