Explanation:
Filtration is a separation technique in which solid particles suspended in liquid medium are separated by allowing the mixture through the pores of the filter paper. By this solid particles get collect on filter paper and liquid drains out from the pores of the filter paper.
The chronological order for given steps will be:
- Weigh and fold the filter paper.
- Place the filter paper in the funnel, then place the funnel in the Erlenmeyer flask.
- Allow the solid/liquid mixture to drain through the filter.
- Use water to rinse the filter paper containing the mixture.
- Weigh the dried filter paper and copper.
Answer:
53 meters = 53000 millimeters
Explanation:
In this question we have to convert meters into millimeters .
By metric conversion,
Since, 1 meter = 1000 mm
Therefore, 53 meters = 53 × 1000
= 53000 millimeters
53 meters = 53000 millimeters is the answer.
I'm curious on what it is but I wish I could help
i. When an acid reacts with metal, a salt and hydrogen are produced:
ii. When oxygen and metal react, metal oxide forms also known as rust
iii. metal and water produce hydrogen gas
Answer : The correct option is (c) 
Explanation :
The given balanced chemical reaction is,
From the balanced chemical reaction, we conclude that
As, 3 moles of 
react to give 2 mole of 
So, 1 mole of react to give moles of
Thus, the conversion factor needed to convert the number of moles of to the number of moles of produced is
Hence, the correct option is (c)
