Resistance depends on there properties of a wire:
- length (the longer the more resistance)
- area (the less area = more resistance and vise verse more area = less resistance)
- resistivity (the more resistivity the resistance)
Hope this helps :)
Answer:
=933.3 grams
Explanation:
Magnesium reacts with oxygen producing magnesium oxide according to the following equation.
2Mg₍s₎ + O₂₍g₎→ 2MgO₍s₎
From the above equation, 2 moles of Magnesium produces 2 moles of magnesium oxide. Therefore the ratio of magnesium to magnesium oxide produced is 1:1
1 mole of magnesium oxide has a mass of: 24+16 =40 grams
560 grams of magnesium=560/24 moles
=70/3 moles.
Since the ratio is 1:1 the reaction produces 70/3 moles of magnesium oxide.
70/3 moles of MgO= 70/3 moles× 40 grams
=933.3 grams
In most cases, carbon shares electrons with other atoms (usual valence of 4). This is because carbon typically bonds with elements which have a similar electronegativity. Examples of covalent bonds formed by carbon include carbon-carbon, carbon-hydrogen, and carbon-oxygen bonds
Answer:
storage solution , deionized water, stabilizes
Explanation:
A pH meter is a scientific device or instrument that is used to measure the pH of a given aqueous solution thereby determining the nature of the solution whether it is acidic or basic or neutral.
While using the pH meter or taking the measurement using the pH meter --
- it should be kept in a storage solution for effective working.
- Before using the device, it is rinsed with a deionized water and pat dry.
- Record the measurements when the pH meter stabilizes.
