how do i get my skin perfect without expensive products? I'm asking bc my face and neck have been massively breaking out with pimples and sweat bumbs. i can go out in public its so bad plsss help
Answer:
if you are a teen then its pretty normal as during the age of adolescent sweat gland become active and pimples take place on you face , no need to worry at this your face will become beautiful again .
but if you are above 25 then it is a time to worry , you should consult a doctor or you can use alovera jel or any other home remedies. :)
I am wondering how to find out the blood type of my grandson...my daughter is A+..father is in question...she is stressed to the max on the father of this baby boy.
Answer:
A person can identify their blood type at home using a rapid blood typing kit. Using the kit requires a person to pierce a finger with a needle. The kit comes with a card that contains chemicals known as reagents. These test for the presence of the antibodies and Rh factor.
Explanation:
Just like eye or hair color, our blood type is inherited from our parents. Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive. For example, if an O gene is paired with an A gene, the blood type will be A.
What is the chemical reaction taking place?

Explanation:
HELLP PLEASE
_ Na+Cl 2 -> _NaCl
reactant side number of atoms?
Na = ?
Cl = ?
Product side number of atoms?
Na = ?
Cl = ?
what is the final equation?
_ Na+Cl 2 -> _NaCl
Answer:
2Na+Cl2 -> 2NaCl
Explanation:
1Na+1Cl 2 -> 1NaCl (i'm assuming they want you to balance it so ill start with 1)
Na = 1
Cl = 2 (it is 2 because it is Cl2, meaning that there are 2; but remember that you cannot change this number only coefficients)
Na = 1
Cl = 1
We need to have 2 Cl on the product side
1Na+1Cl 2 -> 2NaCl
Now we need 2 Na on the reactants side
The final equation is
2Na+Cl2 -> 2NaCl
Now it is balanced
Na = 2
Cl = 2
--
Na = 2
Cl = 2
Al(s) + NiSO4(aq)
Balance
Answer:
[tex]2Al(s) + 3NiSO4 --> Al2(SO4)3 + 3Ni[/tex]
Explanation:
This reaction type is a single replacement. The format of a single replacement is:
[tex]A+BC --> B+AC[/tex]
A= Al
B= Ni
C= SO
The coefficient 3 for Ni would become a subscript for AC. After you plug those into the reaction you need to count how many of each are on the left side and try to get the same number on the right side. Both sides must be equal to have a balanced equation.
Areas in Mexico and Central America are known as
mole equations please help me :(
Answer:
A. 0.48mol O2
Explanation:
The balanced equation is given as follows:
2CH3OH + 3O2 → 2CO2 + 4H2O
This shows that 2moles of CH3OH is required to react with 3 moles of O2
If 0.32 moles of CH3OH are reacted, then;
0.32 × 3/2 moles of O2 is required
= 0.96/2
= 0.48mol of O2
If 0.525 moles of O2 are produced, how many moles of KClO3 are decomposed?
Answer:
B. 0.35mol KClO3
Explanation:
The balanced equation in this question is given as follows:
2KClO3 → 2KCl + 3O2
Based on the chemical reaction;
2 moles of KClO3 decomposes into 3 moles of O2
If 0.525 moles of O2 are produced, then:
= 0.525 × 2/3
= 1.05/3
= 0.35mol of KClO3 is decomposed.
Equilibrium constant Kp for the reaction P4(s) + 6Cl2(g) 4PCl3(l) Kp = 1/ P6Cl2 Kp = P4Cl3/ P6P4 Kp = P4Cl3/ (P6P4) (P6Cl2) Kp = 1/ (P6P4) (P6Cl2)
Answer: [tex]K_p=\frac{1}{[p_{Cl_2}]^6}[/tex]
Explanation:
Equilibrium constant is defined as the ratio of pressure of products to the pressuure of reactants each raised to the power their stoichiometric ratios. It is expressed as [tex]K_p[/tex]
For the given chemical reaction:
[tex]P_4(s)+6Cl_2(g)\rightarrow 4PCl_3(l)[/tex]
The expression for [tex]K_p[/tex] in terms of gaseous is written as:
[tex]K_p=\frac{1}{[p_{Cl_2}]^6}[/tex]
I could swear all of these are nobles gases but here’s the question.
Which one of these is NOT a Noble Gas
A) Argon
B) Helium
C) Xenon
D) Neon

Which of the following is not an example for electroplating? A Tin cans for storing food
B Chromium used on bath taps to get shiny appearance
C Copper used for making electrical wires
D To protect iron objects used in machineries, from corrosion
If you answer you will get brainiest
Please answer and thank
Answer:
C. Copper used for making electrical wires
Explanation:
When a coating of a particular metal is applied on another metal, the process is termed as electroplating. The process is carried by the process of electro-deposition. This process is carried on in order to enhance the quality of the objects manufactured. The coating helps in resistance and provides an attractive appearance to the object.
Option C. is not an example of electrocoating because on the copper wires no other metal coating is done. In all the other three options, coating has been done on the object.
HELpPPPPppp!!!!!! will mark brainless
Answer:
A
Explanation:
This is because in the graph shown line A has a quite greater impact of refraction than line B .
Hence, we can conclude that line A has the greater reaction at a faster rate.

Describe how greater distance affects the appearance of an object’s size and brightness
Answer:
Distance also affects the apparent brightness of an object. A distant, but very energetic star can appear dimmer to us than a lower-energy, but closer one. ... Each of their effective temperatures results in a different brightness for the object. The quasar, however, is very far away, and so appears dim.
