a beaker contains 0.250 l of liquid. a student pours 0.00385 L of liquid out of the beaker. How much liquid remains in the beaker? choose the value reported with the correct number of significant figures

Answers

Answer 1

Answer:

The volume of the liquid remaining in the beaker is 0.24615 l

Explanation:

The initial volume of liquid in the beaker = 0.250 l

The volume of liquid the student pours out of the beaker = 0.00385 l

The volume of liquid remaining in the beaker, V, is given as follows;

V = The initial volume of liquid in the beaker - The volume of liquid the student pours out of the beaker

Therefore, we have;

V = 0.250 l - 0.00385 l = 0.24615 l

The volume of the liquid remaining in the beaker is 0.24615 l.

describe how changing the particles changed the atom

Answers

bonds between atoms break and new ones form and energy is either given out or taken in

Changing the particles changes the atoms by converting it to a new substance through bond change.

During a chemical reaction changes occurs in the atoms of an element due to the formation or breaking of bonds.

There is either loss or gain or sharing of atoms between two elements reacting together.

Bonds between atoms break and new ones form and energy is either given out or taken in.

This type of reaction leads to the formation of new substances made up of a new combination of atoms and a different configuration of electrons.

Therefore, because various changes occurs during a chemical reaction, changing the particles changes the atoms by converting it to a new substance through bond change.

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

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

difference between halogens and group 0 elements

Answers

Answer:

Colourless. Although they have similar properties they are not identical. For example, as you descend Group 0 the density of the gas increases as does the mass of a single atom. ... All the halogens exist as molecules, bonding covalently to their own atoms - adding stability as they complete their full outer shells.

The difference between halogens and group 0 elements is that in their electronic configurations the halogens have 1 electron less than the stable octet while the zero group elements have stable octet.

What is electronic configuration?

Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.

Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.

Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

The BCI interpreted his "thoughts" so that he could use a mouse to move a cursor around on a computer screen to type out his words. This device allowed the man to "speak" with his family and friends even after the stroke had damaged most of his brain function. In 2004, doctors placed a BCI in the brain of a paralyzed man, allowing him to use a mouse to move a cursor. He could also type on a keyboard and play video games.
