Answer:
Kinetic Rate Laws. The rate of the crystal violet/NaOH reaction is given by the following generalized rate law. Rate = k [OHG] [CV]. (1) x y. 25. 30.
The reaction was carried out by varying the concentrations of [CV] within the range 1.00 × 10-5 M-7.00 × 10-5 M at 298 K and fixed [NaOH]o=1.67 × 10-3 M and μ=0.085 M (KNO3). The reaction is dependent on the [CV] as observed rate constant (kobs) increases with increase in [CV] as shown in Table 1.
Explanation:
to calculate the room temperature rate constant for the reaction. BACKGROUND. Reaction Chemistry. Chemical kinetics is the study of reaction rates.
We are given with
Cobalt phosphate - CoPO4
We are asked for the net ionic equation for the phosphate dissolving in H3O+
The net ionic equation is
CoPO4 (s) + H3O+ (aq) -----> HPO42- (aq) + Co3+ (aq) + H2O *(l)
The mouth
Amongst the most vital areas to protect are the neck, face and mouth. Though keeping a set of tiger whites will be most people’s primary concern the gum and mouth guards of today also help reduce the risk of concussions and tongue injuries resulting from impacts to the jaw. The most common mouth guards available are “boil and bite” types. These are heated in order to be moulded around the user’s teeth and then form a more resistant solid on cooling. Their main component is poly(ethylene-vinyl acetate) or PEVA, made from the polymerisation of ethene with vinyl acetate.
the synthesis of PEVA by radical polymerisation

Explanation:
Answer
is: mass number stays 184, but atomic number changes.<span>
Beta decay is radioactive decay in
which a beta ray and a neutrino are emitted from an atomic
nucleus.
There are two types of beta
decay: beta minus and beta
plus. In beta minus decay (</span>atomic number Z is increased by one, new element is wolfram W) neutron is converted to a
proton and an electron and
an electron antineutrino.
In beta
plus decay (atomic number Z is decreased by one, new element is hafnium Hf), a proton is converted to a neutron and positron and an electron neutrino, so mass number does not change.
