The danger from radon gas would most likely be greatest in well-insulated homes. It is a toxic gas.
<h3>What is radon gas?</h3>
Radon is a naturally radioactive gas generated from different elements such as uranium or radium.
Radon is generated when these radioactive materials naturally decompose in the soils and/or rocks.
Radon is highly toxic and therefore this gas must be avoided to maintain healthy conditions in a home.

Balanced equation : C. CH₄ + 4Cl₂⇒ CCl₄+ 4HCl
<h3>Further explanation </h3>
Equalization of chemical reactions can be done using variables. Steps in equalizing the reaction equation:
1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c, etc.
2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index (subscript) between reactant and product
3. Select the coefficient of the substance with the most complex chemical formula equal to 1
Reaction
CH₄ + Cl₂⇒ CCl₄+ HCl
aCH₄ + bCl₂⇒ CCl₄+ cHCl
C, left=a, right=1⇒a=1
H, left=4a, right=c⇒4a=c⇒4.1=c⇒c=4
Cl, left=2b, right=4+c⇒2b=4+c⇒2b=4+4⇒2b=8⇒b=4
The equation becomes :
CH₄ + 4Cl₂⇒ CCl₄+ 4HCl
Answer: The momentum of the child and milk together is 58.125 kg.m/s
Explanation:
Momentum is defined as the product of object's mass and velocity.
Mathematically,
![p=mv](https://tex.z-dn.net/?f=p%3Dmv)
where, p = momentum
m = mass of the object
v = velocity of the object
In the given question, we are given that a child of mass 21.0 kg is carrying a gallon of milk having mass 2.25 kg and running with a velocity of 2.5 m/s. Hence, the momentum by both milk and child will be:
....(1)
Given:
![m_{child}=21.0kg\\m_{milk}=2.25kg\\v=2.5m/s\\p=?kg.m/s](https://tex.z-dn.net/?f=m_%7Bchild%7D%3D21.0kg%5C%5Cm_%7Bmilk%7D%3D2.25kg%5C%5Cv%3D2.5m%2Fs%5C%5Cp%3D%3Fkg.m%2Fs)
Putting values in equation 1, we get:
![p=(21+2.25)kg\times 2.5m/s=58.125kg.m/s](https://tex.z-dn.net/?f=p%3D%2821%2B2.25%29kg%5Ctimes%202.5m%2Fs%3D58.125kg.m%2Fs)
Hence, the momentum of the child and milk together is 58.125 kg.m/s
Answer:
C
Explanation:
Angiosperms have developed these adaptations because it attracts pollinators which helps the ecosystem grow.
Answer:
sugar cube is at great pressure
Explanation:
this is because great pressure means its more solid
