What is the freezing point on this graph?
Answer:
Point a becuse it is the closest to -5*
Explanation:
Answer:
-5
Explanation:
Negative numbers get you confused.
- = Negative
5 = Number
You know 5 right?
I I I I I - 5
5 is a really less number already.
If you add a negative it will be double small.
Now lets figure out the problem:
What is the freezing point on this graph?
-5 is the smallest number
5 is bigger than -5
15 is bigger than 5 and -5
25 is bigger than all the numbers.
I know what your thinking. 25 is totally not the answer. Its the biggest number. Freezing is a very low number. What number is the lowest out of -5, 5, 15, 25. You see -5.
Therefore, -5 is freezing.

How much does a sample of C6H12O6 weigh if it contains 1.7 x 10^28 hydrogen atoms?
Answer:
Explanation:
Glucose has 6 number of carbon atoms, 12 atoms of oxygen and 6 atoms of oxygen
The total number of glucose atom is 24 atoms
The atom of hydrogen is twice that of carbon
that is (6.02 x10^22) x2=1.204 x10^23atoms
the number of moles of hydrogen is solved as follows
1mole = 6.02x10^23 atoms what about 1.204 x10^23=
{(1.204x10^23)/(6.02 x10^23)}=0.2moles
The moles of glucose
1 atom of glucose= 6.02 x10^22 x4 =2.408 x10^23 atoms
moles= { (2.48 x10^23)/(6.02 x10^23)}=0.41moles

Which element has four times as many protons in its nucleus than are found in Neon?
Answer:
Zirconium, Zr, 40
Explanation:
Protons can be found by looking at the atomic number. Neon's atomic number is 10, so just multiply 10 by 4 and you get 40.

Answer:
I hope this helps! Can I have Brainliest plz :)
Explanation:
help me please im in 4th grade and online is frustrating
Answer:
A
Explanation:
The answer is A) because the A container has tightly packed molecules but not as tight as C so that means A is liquid, and C is a solid which makes B a gas
Answer:
The answer would be A
Explanation:
because in the first picture Liquid could be in many shapes like If I put water in my water bottle it would be the same shape as the water bottle.
In the third picture, the solid molecules will always be so close to each other like they will be stick to each other.
In the second picture, It will be separate always, as it cant stick to each other.
I hope I helped you!!!!

Which of the following d shell configurations is likely to be the best magnet?
Answer:
D10 is answer
Explanation:
Magnetism can result from unpaired electrons in a given ion of an element, depending on the spin states of the electrons and d10 is fully filled
The d 10 is the d shell configurations which is most likely to be the best magnet.
What are configurations?Configurations are defined as the way that parts are joined together to form the computer system. The arrangement of electrons scattered throughout the orbital shells and subshells is depicted by the electron configuration of an atom. Divide the periodic table into pieces to represent the atomic orbitals, the areas where electrons are stored, in order to determine an electron configuration. The s-block is represented by groups one and two, the d-block by groups three through twelve, the p-block by groups thirteen to eighteen, and the f-block by the bottom two rows.
Depending on the spin states of the electrons and whether or not d10 is completely filled, magnetism can emerge from unpaired electrons in a specific ion of an element.
Thus, the d 10 is the d shell configurations which is most likely to be the best magnet.
