Answer:when a chemical reaction occurs with only one substance, the atoms of that substance rearranges to form new bonds to make the products.

Explanation: During chemical reaction, the bonds between the reactants are broken and the atom bonds in new ways to form products that are chemically and physically different from the reactants.

Example is the breakdown reaction of hydrogen peroxide(the reactant) into water and oxygen( products). Here, 2 molecules of hydrogen peroxide is broken down to form 2 molecules of water and one molecule of oxygen. The atoms that started out in the hydrogen peroxide molecules are rearranged to form water molecules and oxygen molecules.

Answer:

The atoms of the substance are rearranged

Explanation:

When a chemical reaction involves only one substance, the atoms of the reactant substance rearranges to yield the product substance(s).

Chemical bonds in the reactant substance are broken and new bonds are formed as the atoms in the reactant substance forms the product substance (s).

Light of wavelength 476.1 nm falls on two slits spaced 0.29 mm apart. What is the required distance from the slits to the screen

stich3 [128]

Answer:

The distance is $D = 2.6 \ m$

Explanation:

From the question we are told that

The wavelength of the light is $\lambda = 476.1 \ nm = 476.1 *10^{-9} \ m$

The distance between the slit is $d = 0.29 \ mm = 0.29 *10^{-3} \ m$

The between the first and second dark fringes is $y = 4.2 \ mm = 4.2 *10^{-3} \ m$

Generally fringe width is mathematically represented as

$y = \frac{\lambda * D }{d}$

Where D is the distance of the slit to the screen

Hence

$D = \frac{y * d}{\lambda }$

substituting values

$D = \frac{ 4.2 *10^{-3} * 0.29 *10^{-3}}{ 476.1 *10^{-9} }$

$D = 2.6 \ m$

Institutions that anticipate and recognize significant external forces and modify their strategies and operations will prosper a

vesna_86 [32]

Answer:True

Explanation: External factors are factors outside of an organisation or an institution that has the capacity of either adversely or positively affect the institution or the Organisation.

For an institution to prosper and perform optimally in an economy.or a country, such Institution must put into cognisance the possible external threats that are capable of affecting it, when Organisations or Institution put strategies in place to control or mitigate such externalities,the institution or Organisation will sure Prosper.
