Answer:
1.35×10¹² μg
Explanation:
Mass (Kg) = 1350 Kg
Mass (μg) =?
Thus, we can obtain the mass of the adult rhino in micrograms (μg) by converting 1350 Kg to microgram (μg) as follow:
1 Kg = 1×10⁹ μg
Therefore,
1350 Kg = 1350 kg / 1 kg × 1×10⁹ μg
1350 Kg = 1.35×10¹² μg
Therefore, 1350 Kg is equivalent to 1.35×10¹² μg.
Answer:
c) Wash your hands
Explanation:
A laboratory or most popularly called as lab is a place or facility which provides controlled conditions where some educational research, scientific studies, experiments, testings, can be performed. The place is equipped with sophisticated machines, test samples, hazardous chemicals, instruments etc.
The university or college lab, there is a incharge of the lab called as the lab instructor who is responsible for all the belongings of the lab and the safety of the experimenter or the students.
After performing some experiments or testing with some chemicals, the last and the most important thing we need to do is to wash our hand with soap or hand wash. it is very important because we touch many test samples and hazardous chemical which might go inside our mouth or eyes accidentally, which might be harmful to us.
So, it is important to wash our hand at last before leaving the lab.
According to VSEPR theory, what causes water molecules to have a bent shape?
Answer: Out of all the options presented above the one that best represents what causes water molecules to have a bent shape according to VSEPR theory is answer choice B) repulsive forces between specific lone pairs of electrons. the bond angle in a water molecule is bent.
I hope it helps, Regards.
<span>When an ionic bond is formed between sodium (na) and chlorine (cl), the resulting molecule is called halite (salt). Ionic bonds involve the transfer of valence electrons. When this occurs between metals and non-metals, the metal loses an electron (becoming a cation) and the non-metal gains an electron (becoming an anion).</span>
2 elements with same properties as K could be rubidium and sodium. Elements in the same column (vertical) will have similar properties to each other
Mg has 12 protons- this is given on the (generally) the top left of the element on the periodic table. We know protons have a positive charge so to make the element neutral there would be 12 electrons to balance the protons. The neutrons is usually the same number as the protons but since the majority of an atoms weight is in protons and neutrons- electrons mass in negligee it’s so small- you can subtract the number of protons from the mass number. In this case : 24-12= 12. So there are 12 neutrons
