Match the elements to their periodic table groups based on their uses or properties.
{Element is used as a disinfectant}
{Element important for the proper}
{functioning of the human body.}
{Element always stored under oil.}
{Compounds of this element are
used in manufacturing of paints.}
group 3–12
group 1
group 17
group 2
Answer:
group 3–12used for manufacturing paints and plastic
group 1 stored under oil they are very reactive
group 17used as a disinfectant
group 2 used to reduce stomach acid
Explanation:
The elements that are used as disinfectant comes under the group of halogens. So, group 17.
What is meant by the group in a periodic table ?The group is defined as a column in the periodic table, that contains the elements having the same number of valence electrons.
Here,
1) Element is used as a disinfectant.
The elements that are used as disinfectant comes under the group of halogens. So, group 17.
2) Element important for the proper functioning of the human body.
The compounds of group 2 elements are used for the neutralization of the acids in stomach.
3) Element always stored under oil.
To avoid the oxidation of the elements, the group 2 elements are always stored in oil.
4) Compounds of this element are used in manufacturing of paints.
The elements like Zin, Cobalt, Bromine, etc. are used to make paints. So, group 3 - 12.
Hence,
The elements that are used as disinfectant comes under the group of halogens. So, group 17.

How can embroidery machines help the environment? Positive and Negative Impact
Answer:
When considering the environmental impact of a sewing machine, it is unlikely that this common household appliance immediately conjures images of ecological threat. However, the sewing machine plays a leading role in the fashion industry, which, according to a report by the Ellen MacArthur Foundation, is one of the largest sources of pollution in the world. The report suggests that the textile and fashion industries produce more pollution than aviation and international shipping combined.
Also, with the production of sewing machinery projected to exceed $7 billion this year in China alone, the distribution of those machines will have a massive impact on greenhouse gas emissions. The mass production and distribution of sewing machines, both industrial and domestic, also requires tons of packaging material which negatively impacts the environment. Lonely Whale and the Point Break Foundation estimate that by 2025 there will be one ton of plastic for every three tons of fish in the ocean. Even more alarming, the United Nations suggests that by 2050 there will be more plastic than fish.
Modern domestic sewing machines are made from plastics and polymers, which increases affordability. It also increases the likelihood that consumers will replace rather than repair, especially in the case of handheld sewing machines, which are a growing novelty. With sewing machines constituting an increasing proportion of the millions of tons of household appliances which end up in landfills, this also poses a significant environmental concern.

What is the area of a car that touches the road if the car’s weight on that tire is 288 N and the pressure exerted on the road is 36 Pa?
Answer:
Car's touch area = 64 m²
Explanation:
Given:
Weight of car = 3,072 N
Pressure = 48 pa
Find:
Car's touch area
Computation:
Area = Force / Pressure
Car's touch area = 3,072 / 48
Car's touch area = 64 m²
Answer:64m2
Explanation:
As we know pressure is equal to force divided by unit area so if we rearrange the equation and isolate area we get area is equal to force divided by pressure exerted. By putting values we get 64m2.
Which of the following expressions are correct for variation of weight of a substance on Earth?
