plz help meh, I think there is trick question!!!

Answers

Answer:

Explanation:

Atoms of each element contain a characteristic number of protons. In fact, the number of protons determines what atom we are looking at (all atoms with six protons are carbon atoms), the number of protons in an atom is called the atomic number. In contrast, the number of neutrons for a given element can vary.

Scientist at the CDC (Center for Disease Control) in Atlanta, GA are currently developing and testing new treatments and vaccines for the coronavirus. What kind of research are they conducting?

Answers

Answer:

Applied research

Explanation:

The process of developing a new vaccine involves the use of known scientific theories to address specific problems. Here, the outcome of several basic research are put into use to arrive at a targeted outcome. This outcome/product can be continuously modified (if it shows early promise) until the desired effect is achieved and if no "promise" is discovered at critical points of this research, work on this theory (for this research) is suspended another theory is pursued.

This process (described above) in which scientists continuously develop new treatments and/or vaccines and continuously subject it to testing until the desired effect is achieved can be referred to as Applied research.

google takes its name from a conversion prefix. What is it and how big is it

Answers

Answer:

Giga, 1x10⁹.

Explanation:

Hello,

In this case, if we chew over Google's name, we can see that it suggests the word Giga which in conversion units context accounts for the Giga prefix (G) which has a value of 1x10⁹.

For instance 1 meter in gigameters is:

[tex]1m*\frac{1Gm}{1x10^9m}=1x10^{-9}Gm[/tex]

Which suggests that it is a huge unit and it makes sense considering the raft of information Google handles.

What most likely occurred during this demonstration?
In a science demonstration, a teacher mixed zinc (Zn)
with hydrogen chloride (HCI) in a flask and quickly
attached a balloon over the mouth of the flask Bubbles
formed in the solution and the balloon inflated,
O The Zn and HCl both retained their identity
Either Zn or HCI, but not both, retained its identity
O Evaporation of one of the substances occurred
One or more new substances formed

Answers

Answer:

Hydrogen gas and a salt formed at the end of the reaction.

Explanation:

Hydrogen Gas has formed which inflated the balloon

Usually, metals and acids react to form a salt and Hydrogen Gas.

Here's what happened:

Zn (s) + 2HCl (aq) →  [tex]ZnCl_2[/tex](aq) +[tex]H_2[/tex](g)

Cheers :)

Answer:

One or more new substances formed.

Explanation:

This is an example of a chemical property because bubbles formed, and the mixture produced a gas which allowed the balloon to inflate. The production of bubbles is an indicator of a chemical change. When a chemical change occurs, one or more new substances form as a result.

How do scientists determine the number of neutrons in an isotope of an atom? O They find the number of protons. 0 They add the number of electrons and protons. They divide the atomic mass by two. They subtract the atomic number from the atomic mass. ​

Answers

Answer:

The three naturally-occurring isotopes of hydrogen. The fact that each isotope has one proton makes them all variants of hydrogen: the identity of the isotope is given by the number of protons and neutrons. From left to right, the isotopes are protium (1H) with zero neutrons, deuterium (2H) with one neutron, and tritium (3H) with two neutrons.

The term isotope is formed from the Greek roots isos (ἴσος "equal") and topos (τόπος "place"), meaning "the same place"; thus, the meaning behind the name is that different isotopes of a single element occupy the same position on the periodic table.[2] It was coined by a Scottish doctor and writer Margaret Todd in 1913 in a suggestion to chemist Frederick Soddy.

The number of protons within the atom's nucleus is called atomic number and is equal to the number of electrons in the neutral (non-ionized) atom. Each atomic number identifies a specific element, but not the isotope; an atom of a given element may have a wide range in its number of neutrons. The number of nucleons (both protons and neutrons) in the nucleus is the atom's mass number, and each isotope of a given element has a different mass number.

For example, carbon-12, carbon-13, and carbon-14 are three isotopes of the element carbon with mass numbers 12, 13, and 14, respectively. The atomic number of carbon is 6, which means that every carbon atom has 6 protons, so that the neutron numbers of these isotopes are 6, 7, and 8 respectively.

A i think is the answer

given: f(x) 3x-1. g(x) 2x^2-3
=(3x-1) + (2x^2-3)
= 3x-1 + 2x^2-3
=5x^2-4

can someone tell me if its correct, im not sure if i am ;-;​

Answers

Solution:

f(x) = 3x - 1 = 0

f(x) = x = 1/3

By putting the value of x in g(x), we get

g(x) = 2(1/3)^2 - 3

g(x) = 2(1/9) - 3

g(x) = 2/9 - 3

g(x) = -25/9

Answer:

g(x) = -25/9

Answer:

[tex]2x^{2} + 3x - 4[/tex]

What increases acidity more, nitrile group or chloride group?

Answers

Answer:

The nitrile group

Explanation:

The nitrile group contains the C≡N bond. It should be recalled that triple bond is highly electronegative and withdraws electrons from the C-H bond more effectively than the halogen atom.

The higher effectiveness of the C≡N bond at electron withdrawal greatly reduces the electron density of the C-H bond thereby making the hydrogen atom of the bond highly labile

tony ate 3/4 of the pizza. mike ate 7/16 of the pizza. how much more did tony eat than mike

Answers

Answer:

5/16

Explanation:

make them have a common denominator

3/4 needs to be times by 4

so it's

12/16 then you minus 7/16

the answer is

5/16

Answer: 5/16

Explanation:

Multiply tonys 3/4 by 4 in order to get the same denominator as mike's 7/16. You should get 12/16 since 4x3=12, and now you can subtract the smaller fraction 7/16 from the bigger one 12/16, you should get a difference of 5/16.
